Section Descriptions

The gVCF file contains the following sections:

Metainformation lines start with ## and contain metadata, config information, and define the values that the INFO, FILTER, and FORMAT fields can have.
The header line starts with # and names the fields that the data lines use. These fields are #CHROM, POS, ID, REF, ALT, QUAL, FILTER, INFO, FORMAT, followed by one or more sample columns.
Data lines that contain information about one or more positions in the genome.
If you extract the variant lines from a gVCF file, you produce a conventional variant VCF file.
