WebFor example if we observe fragments of length 50 --- 1000, a position more than 1000 bases from the end of the transcript will contribute a value of 1 to the effective length, while a position 150 bases will contribute a value of F(150), where F is the cumulative distribution function of the fragment length distribution. fbe jd https://ecolindo.net

R: Convert count matrix to CPM, FPKM, FPK, or TPM

Web只有一点差异：RPKM计算的是reads，FPKM计算的是fragments。. single-end/paired-end测序数据均可计算reads count，fragments count只能通过paired-end测序数据计算。. paired-end测序数据时，两端的reads比对到相同区域，且方向相反，即计数1个fragments；如果只有单端reads比对到该区域 ...
