Overview FPKM is implemented at the GDC on gene-level read counts that are … Web19 Jun 2024 · However, as both the FPKM and the TPM value is a transformation of the raw count by a scaling factor f that is dependent on the mRNA length and the library size, adding a pseudocount s to an FPKM or TPM value is equivalent to adding s/f to the raw count and then doing the transformation into FPKM or TPM. Thus, the actual prior distribution is ...
