ADMIXTURE.jl is a Julia wrapper of the popular ADMIXTURE program for estimating ancestry in a model-based manner from large autosomal SNP genotype data sets.
The methodology is described in following papers:
-
D Alexander, J Novembre, and K Lange. (2009) Fast model-based estimation of ancestry in unrelated individuals, Genome Research, 19(9):1655–1664. https://dx.doi.org/10.1101/gr.094052.109

ADMIXTURE.jl requires Julia v1.3 or later. See documentation for usage. It is not yet registered and can be installed, in the Julia Pkg mode, by
(@v1.5) Pkg> add https://github.com/OpenMendel/ADMIXTURE.jl
The original ADMIXTURE software thus ADMIXTURE.jl only support Linux and MacOS.
As a quick example, suppose a set of PLINK files hapmap3.bed, hapmap3.bim, hapmap3.fam are available in the current directory. Then
P, Q = admixture("hapmap3.bed", 3)returns the P matrix (allele frequencies of the inferred ancestral populations) and the Q matrix (the ancestry fractions). The output files by ADMIXTURE are saved in the working directory.
