The main purpose of this page is to provide step-by-step command lines for using LASER to estimate ancestry of 6 targeted sequenced samples (2 HapMap trios) in a principal component space generated using genome-wide SNP data from the Human Genome Diversity Project (HGDP). The HGDP reference panel contains genotype data across 632,958 autosomal loci for 938 individuals from 53 populations worldwide.
