SUPPA2 can be complicated. Are those abundance files straight from Kallisto? They have to come with correct transcript IDs matching the GTF. Even one mismatch and it'll skip the whole thing without much warning.A friend tried SUPPA2 for alternate splicing on 28 RNAseq samples using Kallisto and GENCODE v44. Their preprocessed abundance files seem correct, but SUPPA2 skips all lines with errors. Anyone know the exact abundance file format SUPPA2 requires?
