U-based z-approximation from the Mann-Whitney Rank Sum Test for mapping qualities
This tool calculates the u-based z-approximation from the Mann-Whitney Rank Sum Test for mapping qualities (reads with ref bases vs. those with the alternate allele).
The mapping quality rank sum test can not be calculated for sites without a mixture of reads showing both the reference and alternate alleles.
