featureCounts : Count Reads by Genomic Features

WebHi Tim, The featureCounts() function in Rsubread counts the number of reads mapped to genes or exons and returns a list which includes a read count matrix and annotation information. The returned list object can be easily transformed to a DGEList object which can then be fed into downstream expression analysis packages like edgeR or limma. Web(3) FeatureCounts was used to summarize gene expression levels. Neoantigen expression: Neoantigens whose corresponding mutations were in genes with expression level <1 RPKM in either the specific exon or the whole transcript were filtered out.
