I annotated a VCF of Clinvar variants using vcfanno and would like to create a database using vcf2db. However, there are no samples in the VCF. I tried adding a fake sample in the header and then making a ped file to go along with this, but am getting an error with this:
File "cyvcf2/cyvcf2.pyx", line 932, in cyvcf2.cyvcf2.Variant.gt_bases.__get__ (cyvcf2/cyvcf2.c:22059)
ValueError: range() step argument must not be zero
I am guessing this is because there are no genotypes? Is there anyway to upload this vcf without samples?
