This workflow is used to project a genetic test dataset (in plink format, i.e., .bed/.bim/.fam) into clusters (“ancestral populations”) using ADMIXTURE. First, the cluster file (.P produced by ADMIXTURE) and the test dataset are both subset to contain the same set of variants (Note: this workflow assumes that variants from both the .P and test dataset have been previously harmonized such that variants follow the same naming convention, alleles at each site are ordere
