Hi, I'm using featureCounts from the Rsubread package. But I have a question about the gene length returned by featrureCounts.
I've read the case study here: http://bioinf.wehi.edu.au/RNAseqCaseStudy/, and the combination of featureCounts and edgeR is wonderful.
We often need to get the R/FPKM values from a RNAseq experiment, and I just used the rpkm() function in edgeR. This function takes the gene length as input, which I got by featureCounts. So I wonder how featureCOunts define the gene length? This will affect the result. I've tried google but got little information.
Any help will be appreciated,thank you very much!
