sample larger than population

[anubhabkhan]

Hi,

I get a sample size error when I try to execute:

python popstats.py --file input --pops POP_CI,POP_SI,POP_AR,POP_TH --ancestor POP_ANC --FAB

I have only one ancestral individual. Does the program need more than one outgroup? do all outgroup individuals have to be from the same speceis?

Thanks Anubhab
