countFeatures: Count RNA-Seq Pipeline Genomic Features
Description
Given GRanges, counts number of hits by gene, exon, intergenic, etc
Usage
countFeatures(reads, features)
Arguments
reads
GRangesList object of interval, usually where reads aligned
features
A list of genome annotations as GRangesList
Value
A list of counts by feature
Details
Given a GRanges object, this function performs an overlap against
a previously created set of genomic regions. These genomic
regions include genes, coding portions of genes (CDS),
exons, intergenic regions, and exon groups (which
contain two or more exons)
