| Data processing |
1. We used Novoalign (2.07.00 - Aug 5 2010) to map paired-end 25bp reads to release WS220 (Feb 2011) of the C. elegans genomic sequence obtained from WormBase. If a read was mapped to multiple locations, one location was picked at random (Supplementary file .bam) 2. We extracted properly paired reads mapped only to C. elegans (Supplementary file .bed) 3. For each base pair in the genome, we counted the number of paired-end fragments aligned over it. 4. We normalized base pair counts by dividing by the total number of counts for all base pairs and then multiplying by the total number of base pairs in the genome (Supplementary file .wig) 4. We broke down aligned paired-end fragments into sub-groups by insert size length and repeated steps 3. and 4. for the paired-end fragments in each sub-group.
Genome_build: WS220
Supplementary_files_format_and_content: bam, wig, and bed
