ADMIXTOOLS (or AdmixTools) is a software package that is used mostly to analyze admixture in population genetics. The original version was developed as a set of standalone C programs by Nick Patterson and colleagues and published in 20121. A reimplemented version, ADMIXTOOLS 2, was developed as an R package by Robert Maier and colleagues and published in 20231. Most ADMIXTOOLS programs are based on fitting demographic models to f-statistics, which are calculated from population allele frequencies.

(2012). qpGraph evaluates graph-based models of population relationships with genetic admixture. It estimates likelihoods of graphs with a fixed topology, while adjusting graph parameters to fit observed f-statistics. ADMIXTOOLS 2 adds functions to find optimized graph topologies, similar to programs like Treemix and OrientAGraph. ==Other tools== Related statistical tools in the ADMIXTOOLS software package include qpAdm, qpfst, qpF4ratio, qp3Pop, qpBound, qpDstat, and qpWave. qpDstat and qpWave test whether populations form clades, while qpAdm estimates ancestry proportions. qpAdm is often used in conjunction with CP/NNLS. ==See also== SplitsTree Dendroscope List of phylogenetics software ==References== ==External links== qpGraph software package in Bioconductor 3.8. admixr – R package for reproducible analyses using ADMIXTOOLS
