WebFor use with Bowtie 1, a read is considered to align uniquely if one alignment exists that has with fewer mismatches to the genome than any other alignment (or if there is no other alignment). For Bowtie 2, a read is considered to align uniquely if an alignment has a unique best alignment score (as reported by the Bowtie 2 AS:i field). WebMar 4, 2009 · Bowtie is an ultrafast, memory-efficient alignment program for aligning short DNA sequence reads to large genomes.
