Web除了差异表达分析，其他分析不能用 count 矩阵直接做，需要转成 FPKM 或者 TPM。公式如下： FPKM=\frac{ExonMappedFragments\times 10^9}{TotalMappedFragments\times ExonLength} Web因为在测序之前会对抓取到的RNA进行PCR扩增，所以需要考虑文库深度的对测序的影响，所以需要对上一步得到的稀疏矩阵进行Normalize。 Normalize的方式：每个细胞每个基因的特征计数除以该细胞的特征总计数，再乘以scale.factor（默认10000），然后使用log1p进行对 … WebApr 11, 2024 · TPM (transcripts per kilobase million) is very much like FPKM and RPKM, but the only difference is that at first, normalize for gene length, and later normalize for sequencing depth. However, the differencing effect is very profound. Therefore, TPM is a more accurate statistic when calculating gene expression comparisons across samples. home show palmerston north
