Data processing 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).
Genome_build: hg19
