[Vcftools-help] vcf-isec usage for venn

[Stéphane P. <ste...@vi...>]

I tried and could run a command to compare two vcf files

vcf-isec -p venn_  A.vcf.gz B.vcf.gz

instead of 3 venn regions I get 5 files

venn_0_1.vcf.gz
venn_0_1f.vcf.gz
venn_0.vcf.gz
venn_1.vcf.gz
venn_1f.vcf.gz

could someone explain the meaning of the '0_1' vs '0_1f' and '_1' vs '1f' (and why no _0f ?)

Thanks,
Stephane
