Structure Software for Population Genetics Inference

Structure is a software package for using multi-locus genotype data to infer the presence of distinct populations, assigning individuals to populations, studying hybrid zones, identifying migrants and admixed individuals, and estimating population allele frequencies in situations where many individuals are migrants or admixed. It can be applied to most of the commonly-used genetic markers, including allozymes, microsatellites, RFLPs and SNPs. Unlike GeneClass and WhichRun, which require genetic characterization of potential source populations, Structure can also infer and characterize source populations if they are unknown. A command-line version of Structure is available for Linux/Unix, Dos/Windows, and the Mac OS, while a graphical front package is available for Linux/Unix and Dos/Windows.
