Thanks, got that working. Admixtures sucessfully constrained.
I was able to specify China_UP > East-Asian contribution to reasonable levels without damage to fit of graph.
Now I'm going to decrease Gravettian > WHG contribution to try and lower the CWE drift edge to hopefully flush out some 0 drift edges elsewhere.
