Scoring an empty VCF

[fellen31]

Hi,

Sometimes all variants in a VCF might be filtered out before running genmod.

models will run without error, but fields will be missing in the output header

##INFO=<ID=Annotation,Number=.,Type=String,Description="Annotates what feature(s) this variant belongs to.">
##INFO=<ID=GeneticModels,Number=.,Type=String,Description="':'-separated list of genetic models for this variant.">
##INFO=<ID=ModelScore,Number=.,Type=String,Description="PHRED score for genotype models.">
##INFO=<ID=Compounds,Number=.,Type=String,Description="List of compound pairs for this variant.The list is splitted on ',' family id is separated with compoundswith ':'.>

causing score to fail

Could a VCF without any variants be allowed to pass through genmod?
