The confusion of using TPM (transcripts per million)

WebTPM (transcripts per kilobase million) counts per length of transcript (kb) per million reads mapped: sequencing depth and gene length: gene count comparisons within a sample or between samples of the same sample group; NOT for DE analysis: RPKM/FPKM (reads/fragments per kilobase of exon per million reads/fragments mapped) similar to TPM WebTPM (transcripts per kilobase million) counts per length of transcript (kb) per million reads mapped: sequencing depth and gene length: gene count comparisons within a sample or between samples of the same sample … moa cm01t - koffiecupmachineWebAug 14, 2024 · Your computation of RPKM using edgeR is fine, provided that the gene lengths from EnsDb.Hsapiens.v86 match the gene annotation originally used to generate the gene counts. I don't want to give advice about TPM. edgeR is not designed to produce TPMs and I don't recommend TPMs for downstream analyses. moa.consumerservices flhealth.gov

"WebJun 22, 2024 · The TPM method adds to the previously used RPKM - for single-end sequencing protocols - or its paired-end counterpart FPKM. TPM uses a simple normalization scheme, where the raw read counts of each gene are divided by its length in kb (Reads per Kilobase, RPK), and the total sum of RPK is considered the library size of … " - Edger count tpm
