- VCF 4.3 : "##fileformat=VCFv4.3", the extra meta lines, "#CHROM POS ID REF ALT QUAL FILTER INFO", then a tab-separated line per variant. A missing value (no ID, no ALT, no QUAL, no FILTER, no INFO) is ".". The ALT alleles are joined by commas, the INFO entries by semicolons, a flag written by its key alone, and an INFO value has its ";", "=", ":", "%" and line or tab characters percent-encoded (the reader decodes the same set) - its commas are not, since they separate the items of a list.
