Root Mean Square of the mapping quality of reads across all samples.
This annotation provides an estimation of the overall mapping quality of reads supporting a variant call, averaged over all samples in a cohort.
The root mean square is equivalent to the mean of the mapping qualities plus the standard deviation of the mapping qualities.
