WebReads are first aligned to the genome with STAR and then featureCounts is used to measure gene expression at both the gene- and transcript-level. We can go from raw reads to RPKM values in about 15 minutes for a typical human dataset, with the ability to process hundreds of samples in parallel. Individual samples can then be combined in ... WebI have raw counts data from featureCounts. I actually wanted to do survival analysis. For a specific gene I want to classify the samples into Low and High based on expression cutoff. For that I'm using maxstat package. First I would like to convert raw counts to FPKM. So, I did like following.
