Rates of erroneous SNP calls associated with various causes (Watson genome dataset). "Not verified" means that the SNP was not found in the databases of Watson's heterozygous positions that we consulted. "Not alignable" means that the assembled neighborhood of the SNP did not align to the human reference at 98% identity or higher over at least 200 bp, whereas "Not unique" means that it aligned more than once.
