An exceedingly simple, yet feature-packed, online tool ideal for modeling ancestry with
Global25 coordinates is freely available
HERE. It works offline too, after downloading the web page onto your computer. Just copy paste the coordinates of your choice under the "source" and "target" tabs, and then mess around with the buttons to see what happens. The screen caps below show me doing just that.
Another free, easy to use online tool that works with Global25 coordinates is the Principal Component Analysis (PCA) runner
HERE. Below is a screen cap of me checking out one of the many PCA that it offers.
