WebThat said FPKM is generally better than raw read counts. Not for differential expression analysis. As Rob ( u/nomad42184) explains above, several DE tools simply don’t accept normalised counts as input, and do the wrong thing when force-fed normalised input. This is true for both FPKM and TPM, by the way. http://lbcca.org/can-tmm-be-used-to-compare-genes-within-a-sample
