How to get the unique variants in all 120 bgzip and tabix indexed vcf files using bcf tools ? Each unique variant should be counted as 1 across all samples. After merging all unique variants into a single vcf file, how to rename the chromosome arabic numbers into roman numbers using bcf tools ? Thanks.
