I am running ADMIXTURE analyses at various levels of K. I generally look at more than just the K(s) with the optimal CV value(s) (especially, since my North African and European components don't like to split).
I've noticed between each run the components are always in different orders, meaning if I leave them be the colors for K=n and K=n+1 will not correspond.
My "solution" has been that I would manually sort the components each for each K based on their order in the previous K. (e.g., if in K=10 the first component was maximized in the Onge, then in K=11 I would sort it that the component maximized in the Onge there would be the first component).
There must be a better way to do this? Does anyone have any suggestions?
