WebApr 17, 2024 · The tool requires a common germline variant sites VCF, e.g. derived from the gnomAD resource, with population allele frequencies (AF) in the INFO field. This resource must contain only biallelic SNPs and can be an eight-column sites-only VCF. The tool ignores the filter status of the variant calls in this germline resource. WebDec 19, 2015 · A FILTER field would therefore either contain a single set, or one set per alt-allele. This change is not backwards-compatible since it implies that commas are no-longer allowed as part of the filter string, so an old VCF with commas in the filter name would be parsed incorrectly.
