I am using the GATK to jointly genotype several hundred samples. After this step I would like to do all of my filtering using the GATK, and would like to filter on MAF. Does anyone know if this is possible, or will I have to use Plink to do so?

Thanks!

is the MAF available in the VCF ? do you have any multi-allelic alleles in the VCF (= more than one MAF per line)

No. I was wondering if the GATK had a tool that could calculate MAF from the VCF.

I think every time you're running a GATK tool modifying the genotypes, the AC/AN attributes are re-calculated.

That's good to know. I appreciate the answer! Thanks
