Bowtie2 index to fasta
WebSep 29, 2024 · To evalute read support for the assembly is a three step process. First, you build a bowtie2 index for your assembly. Next, you map your reads and calculate alignment statistics. The align_stats.txt file will provide info on the percentage of read pairs that mapped concordantly,as well as an overall alignment rate. Web$\begingroup$ Apparently, bowtie2 when reading headers will try to understand if the string is a DNA sequence: it does not ignore the content. However, it processes fine. However, …
