Intron spanning reads
Webexon-spanning reads and it soft clips those read bases which could not be mapped. However, the Subread mapping result is su cient for carrying out the gene-level expression analysis using RNA-seq data, because the mapped read bases can be reliably used to assign reads, including both exonic reads and exon-spanning reads, to genes. WebJun 25, 2008 · The intron-spanning reads obtained by mRNA-Seq can also be used to identify cases of alternative splicing and to quantify changes in alternative splicing that occur in different samples 4,5.
