WebMar 26, 2024 · I have downloaded SARC RNA-seq data by HTseq-Count workflow type through TCGAbiolinks. But I need SARC RNA-seq data based on Transcripts Per Million (TPM) value. Can TCGAbiolinks help me to download TCGA RNA-seq based on TPM values? or does this package have any function for converting data set with TPM value … WebNov 2, 2024 · In what scenario are TPM values really useful? Should downstream analysis use TPM or raw count matrix? When I analyzed sc-RNA seq data, the Seurat package …
WebThus, for TPM calculation, raw read counts are first divided by the effective transcript length, which is defined as transcript length - cDNA fragment size + 1. After this, the resulting numbers are scaled linearly to add up to one million. Thus, the sum of all TPM values for a particular sample is always equal to (approximately) 1,000,000.

WebFeb 22, 2024 · Intuitively this seems to make sense, since the TPM values are per million, although of course it relies on the assumption that experimental conditions for the RNA-seq were similar. If the above is a statistical crime, any advice on whether I can do anything meaningful with the TPM values would be appreciated. Thank you!
