WebYou can quickly confirm this by using either samtools depth or samtools mpileup to look at a region with a soft-clipped alignment. You'll note that the soft-clipped region isn't used in the depth/pileup (both tools use the same underlying code, so it doesn't matter which you use). WebTo disable it, use the -B option. It is possible to store precalculated BAQ values in a SAM BQ:Z tag. Samtools mpileup will use the precalculated values if it finds them. The -E option can be used to make it ignore the contents of the BQ:Z tag and force it to recalculate the BAQ scores by making a new align- ment.
