Hi

I have got the vcf file with the SNP informations from four individuals. I want to make a Venn diagram (or another graphical display of the SNPs) of the SNPs? To see how many SNPs are shared and private between these four individuals. Is there a tool who does it. My data looks like this :

##fileformat=VCFv4.1
##contig=<ID=1,length=48143371>
##FORMAT=<ID=GT,Number=1,Type=String,Description="Genotype">
#CHROM  POS     ID      REF     ALT     QUAL    FILTER  INFO    FORMAT  Indi_A   Indi_B   Indi_C  Indi_D
1       50      .       G       C       .       .       .       GT      0       0       0       1
1       55      .       G       T       .       .       .       GT      0       1       0       1
1       267     .       G       T       .       .       .       GT      0       0       1       0
1       271     .       T       G       .       .       .       GT      0       1       0       0
1       366     .       C       A       .       .       .       GT      0       1       0       0

Thanks

Once again, I'm going to suggest UpSetR. A venn diagram with four intersections starts being quite messy.

I dont't know a tool that does that directly.

But you can extract the SNPs that intersects between your individuals manually and then do Venn diagrams.

You can do that with SNPSift for example.
