Hi, I created VCF files for 5 cultivars in the following way:

bcftools mpileup -Ou -f $2 ${1}/all.sorted.dedup.bam | bcftools call -mv -Ob -o ${1}/calls.bcf
bcftools view -i '%QUAL>=20' ${1}/calls.bcf > ${1}/calls-gt-q20.vcf

How can I create a venn-diagram out of those files?

Thank you in advance,
