WebAnd now I used fpm () function to calculate FPKM from counts data. fpkm_data <- fpkm (dds) Error in fpkm (dds) : rowRanges (object) has all ranges of zero width. the user should instead supply a column, mcols (object)$basepairs, which will be used to produce FPKM values Sorry, no idea about what to do now. Web11 Apr 2024 · FPKM (Fragments Per Kilobase per Million mapped fragments) is very similar to RPKM. We divide the number of fragments of a gene by the total sequencing depth, and the ratio is divided by the gene length. Note that, strictly speaking, the gene length mentioned above represents the total length of exons from one gene.
