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.

WebApr 25, 2024 · 0. 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.
