WebJul 23, 2024 · 最常使用的软件是htseq。 可以参考用 htseq-count对reads计数并合并矩阵 。 但是这个方法真的很费时间,所以找到了一个便捷的工具,Featurecounts。 还是要先下载,因为之前我在学习RNA-seq的时候下载了htseq,但是没有下载这个。 #featureCounts 在 subread 这个包里面 conda install subread #建立一个软链接,方便直接调用 ln -s … WebAug 14, 2024 · Get-Content 's -ReadCount parameter sends arrays (batches) of lines read from the input file through the pipeline. Therefore, the automatic $_ variable in the receiving ForEach-Object call then refers to an array of lines rather than a single line, as would be the case without -ReadCount.

Web将读数计数除以每个基因的长度(以千碱基为单位),得到每千碱基reads(RPK, reads per kilobase)。 计算样本中所有RPK值,然后将其除以1,000,000,得到“每百万”缩放因子 ( “per million”scaling factor )。 将RPK值除以“每百万”缩放因子,得到TPM。 因此在计算TPM时,与RPKM、 FPKM相比,唯一的区别是TPM先对基因长度进行标准化,然后对测序深度 … WebDec 15, 2024 · 先说结论:. 学术界已经不再推荐RPKM、FPKM;. 比较基因的表达丰度,例如哪个基因在哪个组织里高表达,用TPM做均一化处理;. 不同组间比较,找差异基因,先得到read counts,然后用DESeq2或edgeR,做均一化和差异基因筛选;如果对比某个基因的KO组和对照,推荐 ...
WebJul 22, 2015 · TPM is very similar to RPKM and FPKM. The only difference is the order of operations. Here’s how you calculate TPM: Divide the read counts by the length of each gene in kilobases. This gives you reads per kilobase (RPK). Count up all the RPK values in a sample and divide this number by 1,000,000.
