WebOct 4, 2024 · Though, TPM, RPKM, and FPKM are designed to normalize the expression levels of genes, it suitable for the comparison within a sample, not cross samples. … WebJun 2, 2024 · The important point is that TPM, like FPKM, is independent of transcript length, whereas “raw” counts are not! The *.normalized_results files on the other hand just contain a scaled version of the raw_counts column. The values are divided by the 75-percentile and multiplied by 1000. This should make the values a bit more comparable …
