Reads mapped to multiple loci

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. WebApr 11, 2024 · This paper proposes the use of weighted multiple linear regression to estimate the triple3interaction (additive×additive×additive) of quantitative trait loci (QTLs) effects. The use of unweighted regression yielded an improvement (in absolute value) in the QTL×QTL×QTL interaction effects compared to assessment based on phenotypes alone …

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. To provide an estimate of loci expression, the reads were proportionally assigned to the determined HLA loci based ... WebApr 21, 2016 · Repeat mapping. Apr 21, 2016. Most of the projects I am involved with deal with mapping reads to repeat regions of the genome. Specifically transposons.
