WebAs CLIP-seq/RIP-seq reads are short, existing computational tools focus on uniquely mapped reads, while reads mapped to multiple loci are discarded. We present CLAM (CLIP-seq Analysis of Multi-mapped reads). CLAM uses an expectation–maximization algorithm to assign multi-mapped reads and calls peaks combining uniquely and multi-mapped reads. WebI have 75% - 90% of uniquely mapped reads. % of reads mapped to multiple loci ranges from 15% to about 5% - could this be the reason for the observed low assignment rate? Would you suggest to (i) accept this and go on, or (ii) try to count the multiple loci reads, too (which is possible in featurecounts, if I am not mistaken). how to say lumateperoneWebJul 10, 2024 · Then, I used STAR to align them to the human reference genome but got an unexpectedly high percentage of unmapped reads. For my ~20 samples, I got 75-86% uniquely mapped reads, 4.3-5.6% multi-mapping reads and 10-19% unmapped reads: too short.

We present CLAM … 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] .

WebDec 22, 2012 · Owing to the highly conserved nature of the HLA alleles, many reads mapped to multiple alleles and even multiple loci, and thus the assignment between an individual read and an individual allele or locus was frequently ambiguous.
