Genotype Extraction Format from VCF file

Question

[MK2000]

When you extract genotype data for certain samples in a VCF file, is the resultant file in GT.FORMAT still technically a VCF file in itself? or if you wanted these extracted genotypes in their own vcf, do you somehow have to convert this to .vcf?

[Pierre Lindenbaum]

it's not clear. Give use an example of "resultant file" and"extracted genotypes "

While your question is unclear, if you select lines from your vcf and keep the header intact then yes, that's still a vcf. If you start to do more tampering than you are likely breaking the specfications.
