WebIn the Bowtie2 manual it states that the gap between the alignment score of the "best" mapping position and the alignment scores of any secondary alignments will significantly influence the MAPQ. So maybe those MAPQs would be greater than 1 if the second alignment score was substantially lower than the primary alignment score.

WebJun 7, 2024 · My understanding of BWA's output is that if a read maps perfectly to multiple genomic locations, it will be given a high mapping quality (MAPQ) score for both locations. Many people expect that a read that maps to at least two locations can have (at best) a 50% probability of mapping to one of those locations (i.e. MAPQ = 3).
