Unique Variants for a sample

Question

[kat.bi]

I have multiple .vcf files for different samples/ IDs. I need the unique set of variants or entries for a particular sample alone excluding the variants existing in all other samples. So could bcftools/ any other tools help with that? Which are the fields in VCF that I would need to consider to achieve this?

you want bcftool isec

[kat.bi]

I used that, but only giving few fields in output. How to get all fields as in the original .vcf?

Can you help more elaborately on further commands to filter/query using isec based on allele uniquenes as I'm getting large no. of samples after isec --complement? @Pierre Lindenbaum
