"WebJul 9, 2015 · TPM is very similar to RPKM and FPKM. The only difference is the order of operations. Here’s how you calculate TPM: Divide the read counts by the length of each gene in kilobases. This gives you reads per kilobase (RPK). Count up all the RPK values in a sample and divide this number by 1,000,000. " - Raw counts fpkm
