WebJan 26, 2024 · With RPKM or FPKM, a problem is normalization to the total number of reads. The total number of reads is dominated by genes whose transcripts are long or that are highly expressed. Thus small percentage differences in expression of such genes among samples can lead to artifactual differences among genes normalized to total reads. WebIn this workflow, the probability of sampling a fragment from a long transcript is higher than from a short one. Therefore, it makes sense to normalize read counts by transcript length (e.g., TPM, RPKM, FPKM). However, in 10x gene expression assays, this gene-length bias does not exist. Therefore, we do not advise on normalizing UMI counts by ... gb19196
