I have never run more than 3 populations, because I have never found a situation where we could reliably assign more than 3 ancestries. I forget if the underlying code can handle more than three populations, I suspect that there might be a few hiccups if you did that, but they would be easily fixable. If you feel confident that you can reliably assign four local ancestries, I can help you make it work.
One workaround would be to combine two of the four ancestries (typically, the most difficult to distinguish) and treat them as a single ancestry.

Dear Simon,
I have tried to run my admixed population with 2 and 3-population models in your document. However, structure analyses indicated 4 ancestral populations in my cohort.
Could you suggest me how I can find a sample script for 4-population tracts analyses?
Thankyou for your great software and help.
Cheers, James
