WebOct 16, 2024 · As I understand, step 1 of the mapping (global) refers to standard alignment of the reads, and step 2 (local) is an attempt to rescue reads crossing the ligation junction. End to end mapping is still used after trimming the portions of reads crossing a ligation junction in both cases as I understand. So the question is whether or not it would ... WebBowtie 2 also supports end-to-end alignment which, like Bowtie 1, requires that the read align entirely. There is no upper limit on read length in Bowtie 2. Bowtie 1 had an upper limit of around 1000 bp. Bowtie 2 allows alignments to overlap ambiguous characters (e.g. N s) in the reference. Bowtie 1 does not. blizzcon skins overwatch
