Bowtie2 on Ivy Windows VMBowtie2 is a memory-efficient tool for aligning short sequences to long reference genomes. It indexes the genome using FM Index, which is based on Burrows-Wheeler Transform algorithm, to keep its memory footprint small. Bowtie2 supports gapped, local and paired-end alignment modes. Alignment to a known reference using Bowtie2 is often an essential first step in a myriad of NGS analyses workflows. Bowtie2 Usage Alignment using bowtie2 is a 2-step process - indexing the reference genome, followed by aligning the sequence data. Create indexes of your reference genome of interest stored in reference.fasta file: bowtie2-build [option(s)] <reference.fasta> <bt2-index-basename> This will create new files with the provided basename and extensions .
