WebBowtie2 supports gapped alignment with affine gap penalties, without restrictions on the number of gaps and gap lengths. Bowtie supports reads longer than 50bp and is generally faster, more sensitive, and uses less memory than Bowtie. Bowtie support only end-to-end alignments, while Bowtie2 supports both end-to-end and local alignment. http://cncbi.github.io/Bowtie2-Manual-CN/
