Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

Short read trimming: Prinseq to remove short reads (-min_len 30) trim the first 10 bp on the 5’-end (-trim_left 10), trim reads with low quality on the 3’-end (-trim_qual_right 25) and filter low complexity reads (-lc_method entropy \-lc_threshold 65).  We used FASTQC to determine overrepresented sequences and removed those using cutadapt (-e 0.15 –m 30). We then used Prinseq to remove orphan pairs less than 30bp in length followed by removal of nextera adapters using Trim Galore  (--stringency 1).
Read alignment: reads were aligned to the hg19 genome with STAR using the following options (-outFilterType BySJout \--outFilterMultimapNmax 20 \--alignSJoverhangMin 8 \--alignSJDBoverhangMin 1 \--outFilterMismatchNmax 999 \--outFilterMismatchNoverLmax 0.04 \--alignIntronMin 20 \--alignIntronMax 1000000 \--alignMatesGapMax 1000000 \--outSAMstrandField intronMotif ).
Per-gene read assignement: aligned reads were converted to counts for every gene using HTSeq (-m intersection-nonempty \-s no).

    <Summary>
We used single cell RNA sequencing on 466 cells to capture the cellular complexity of the adult and fetal human brain at a whole transcriptome level. Healthy adult temporal lobe tissue was obtained from epileptic patients during temporal lobectomy for medically refractory seizures. We were able to classify individual cells into all of the major neuronal, glial, and vascular cell types in the brain.
