WebAn important issue with ChIP-seq data concerns the inclusion of multiple mapped reads (reads mapped to multiple loci on the reference genome). Allowing for multiple mapped reads increases the number of usable reads and the sensitivity of peak detection; however, the number of false positives may also increase [1] . WebJul 21, 2006 · For the remaining one-third of the reads, which each mapped to multiple loci (up to 25,044 loci), we normalized the number of reads by the number of genomic hits and assigned this normalized hit count equally to all the loci; thus, a piRNA read with four perfect genomic hits contributed a quarter of a count to each of its four loci.
