So, I have set up an automated job that will do just that: use pretty much every population available to me under only a few conditions:
- Each population must have at least 5 individuals
- It must have the same 166,462 SNPs on which the test is based
- It must not be from a group not covered by the test (e.g., Australo-Melanesians or Native Americans)
The average admixture proportions of different populations will be put in this spreadsheet as they are calculated, which will probably take several days.
