TESS
From Vd
General Description
TESS implements a Bayesian clustering algorithm for spatial population genetics analysis. It performs individual geographical assigment and admixture analysis. It is designed for seeking genetic discontinuities in continuous populations, and for correcting for stratification in association studies. Given individual geographical locations, the program builds a prior (spatial) network structure indicating genetic relatedness. TESS returns graphical display of geographical cluster assignments and textual output of the admixture Q matrix.
