Q1: I have a VCF file containing 518 samples, which belong to 25 populations. How can I use angsd to specify the samples to be included for analysis when the input is a VCF file? The -b parameter seems to be applicable only for BAM files. Since I need to calculate FST between these populations, I'll have to compute the SFS for each population separately.
Q2 : I tried splitting the total VCF file into subsets according to population information and calculated the corresponding SFS for each population using the subset VCF files. However, some population VCF files produced the following error during the calculation: [ERROR]（safreader.cpp:306）ret==band[1]*sizeof(T) && band[0]+band[1]<=saf->nChr+1. How can I figure this out?
