To determine consistent global ancestry estimates across studies, each subject was run through a standardized pipeline, based on SNPweights67 of 10,000 ancestry informative markers genotyped in a reference panel including 2911 unique subjects from 71 diverse populations and six continental groups (K = 6)68 (https://github.com/nievergeltlab/global_ancestry). Pre-QC genotypes were used for these analyses.
