Hi everyone! i am trying to make venn diagram containing both common and unique variants through VcfToolz but getting unique variants in output venn diagram, common variants are missing may be due to different quality and depth values. if i try to give it vcf files with first five columns only e.g., #CHROM POS ID REF ALT, It gives following error

Traceback (most recent call last):

**tried both commands for making venn diagrams**
**$ vcftoolz compare --exclude_ref --exclude_missing --exclude_filtered  ERR759314_filt.vcf ERR1395564-filt.vcf ERR757814_filt.vcf ERR759307_filt.vcf > summary-exclude-ref.txt
$ vcftoolz compare ERR759314_filt.vcf ERR1395564-filt.vcf ERR757814_filt.vcf ERR759307_filt.vcf > summary.txt**

your suggestions will be really appreciated
