WebFeb 25, 2015 · All bowtie2 tests were run using 20 CPU threads, and default aligment options: Specificity and Sensitivity While targeting maximum performance, nvBowtie is designed to match Bowtie2 as closely as possible, with the explicit goal of mantaining the same specificity and sensitivity characteristics. WebThe minimum, average and maximum read lengths for the Ion Torrent reads were 4 nt, 191 nt and 2,716 nt, respectively. Bowtie 2 was run in ‘local’ mode, meaning that some nucleotides at either extreme of the read could be omitted (that is, ‘soft trimmed’ or ‘soft clipped’) as determined by a Smith-Waterman–like scoring scheme.

Yes, this is expected. If a read maps equally well to two different locations in the reference database, then the minimum probability that read maps to another location is 0.5. MAPQ scores are ten times the negative log10 of the probability of a mismatch, so a mismatch probably of 0.5 would lead to a maximum MAPQ score of − 10 ∗ l o g 10 ...
