VCF Genotype Annotator

The VCF Genotype Annotator will take an existing VCF file and add a new sample to it. The sample name is set via the second positional argument. The sample’s GT field is pre-populated with a default value given by the third positional argument. Options are 0/1, 1/1, 0/0, or ..

By default the output VCF will be written to a .genotype.vcf file next to your input VCF file. You can set a different output file using the --output-vcf parameter.
