WebDescription. bowtie2 (indexBaseName,reads1,reads2,outputFileName) maps the sequencing reads from reads1 and reads2 against the reference sequence and writes … Web13.2 Bowtie2-build-l to build the index files. In order to run a Bowtie2 alignment, one needs a complete Bowtie2 database, in other words a .fna (fasta) file that has been indexed using the command bowtie2-build-l. This is the first part of the pipeline for the alignment step. You can therefore provide your own merged fna file for Bowtie2 to ...

WebAlignment speed depends largely on the read length and alignment parameters used. Allowing many mismatches and using a short seed length (which is the default option for Bowtie 1, see below) tends to be fairly slow, whereas looking for near perfect matches can align around 5-25 million sequences per hour (using Bowtie 1).
