Callable - The total number of sites sequenced with 4 or more reads. Each read has less than 10% likelihood
of being misaligned.
pRegion - The callable sites occurring Poznik et al. (2013), Sequencing Y Chromosomes Resolves Discrepancy in
Time to Common Ancestor of Males Versus Females. Retrieved Feb 17, 2018 from Science. These regions are a superset of the combBED used by Adamov's group. The sites include areas outside of Big Y's targetted sequencing regions.
Low Coverage - The sites having less than four total reads. These areas cannot be called reliably using
automation, but may contain valuable information after manual inspection.
Poor Coverage - The sites having more than four reads, but the aligner indicates a high likelihood the results
may not be correct.
Y-DNA % - The percentage of the known GRCh38 human Y chromosome with at least a single read.
