single sample VCF - add flag to FILTER based on AF in genotype
I am trying to either hard filter or flag variants where the AF < 0.05. The VCF was generated using MUTECT2 in GATK22.214.171.124. The VCF is a single sample VCF, and does not have 'AF' in the INFO field. It does have AF in the FORMAT field. I did try using VariantFiltration with --genotype-filter-expression "AF < 0.05" --genotype-filter-name "MAF<5%", but I have sinced learnt that this does not add a flag to the FILTER field. Any help appreciated.
