In my earlier posts where I gave a short intro to using Plink I distributed a data set termed PHLYO. One thing I did not mention is that I've also been running it on Admixture. But here's an important point: I ran the data set 10 times from K = 2 to K = 15. Why? Because the algorithm produces somewhat different results on each run (if you use a different seed, which you should), and I wanted to not be biased by one particular result. Additionally, I also turned on cross-validation error, which gives me a better sense of which K's to trust. But after I select the K which I want to visualize which replicate run will I then use to generate the bar plots? I won't pick any specific one. Rather, I'll merge them together with an off-the-shelf algorithm. Additionally, I also want to sort the individuals ...
