Handling multi-mapped reads in RNA-seq - ScienceDirect

WebYou can run bowtie2 with default settings, but employ '-k 2', which will report up to two mapped location per read/pair. The resulting SAM file can then be filtered using the XS:i flag, which indicates the second best mapping location, i.e. it identifies non-uniquely mapping reads. Below is some dummy code to illustrate: Webcufflinks(alignmentFiles) assembles a transcriptome from aligned reads in alignmentFile and quantifies the level of expression for each transcript .
