Dear all,

I used featureCounts to get counts for each exon, but I want to get a sum of the counts assigned to each exon within the same gene. The results table is like below: for gene1165795 there are 4 exons, and gene1165796 has 12 exons. I have more that 80,000 exons belonging to 30,000 genes. So I woluld like to ask if there is a quick and easy way to get the sum? Thank you in advance. Best reagrds, Yanfang
