in the admixture estimate field, simple to use, and well-
documented.  My main goal was to analyze the data in the recent
Xing et al. (2010) paper. It's unfortunate that many recent
papers do not have their data online, or they hide them behind
various institutional controls, but the data in that paper (a
total of 40 populations typed for a quarter million markers) is

EURO-DNA-CALC, making it more powerful and extending it with
non-European populations. There are a few aspects that are
particularly important:   1. You can't assume that people will
have the computing power and know-how to go through various
steps to run ADMIXTURE themselves.   2. The alternative of
having people send me their genotype data is impossible because
of legitimate privacy concerns and the o
