Reads数和碱基数

Web首先,需要明确一点: 数据量大小其实就是碱基的个数。. 那么,数据量大小的计算方法是:. 单端测序. 数据量=reads长度 * reads个数 (reads长度很容易得知,reads个数等于测序所得到的fastq文件的总reads数) 2. 双端测序. 数据量=单端reads长度 * 单端reads个数 * 2. 通常 … WebRead (biology) In DNA sequencing, a read is an inferred sequence of base pairs (or base pair probabilities) corresponding to all or part of a single DNA fragment. A typical sequencing experiment involves fragmentation of the genome into millions of molecules, which are size-selected and ligated to adapters.
