WebAug 31, 2024 · FPKM is a normalized gene expression metric and an acronym for fragments per kilobase per million mapped reads. FPKM normalizes for both sequencing depth and genome size. Those specific packages want non-normalized counts as the expression metric. This means the number of reads mapped to a particular gene or feature. WebNOTE: This video by StatQuest shows in more detail why TPM should be used in place of RPKM/FPKM if needing to normalize for sequencing depth and gene length. DESeq2 …
