convert PLINK file to genepop

Question

[age00]

Hello, I was wondering if anyone knows how to convert a PLINK file (.ped or .bed) to genepop.

I have PGD spider but it doesn't use population information so the output file is only one pop.

I stratified allele frequecies frequencies (.frq) but this file doesn't work in PGD.

Any ideas?

Thanks!
