Research direction

Start with the bcftools concat behavior for --allow-overlaps and --remove-duplicates, then compare it with bcftools merge and its --info-rules argument. Use duplicate entries from A.vcf.gz and B.vcf.gz to define the expected INFO-field merge result and verify that configurable duplicate handling is complete.

Description

enhancement

I've got two VCF files from the same sample. I can combine them with bcftools concat --allow-overlaps A.vcf.gz B.vcf.gz but I can't find a way to merge identical entries. They can be removed with --remove-duplicates, but I want to merge their INFO entries similar to the behaviour of bcftools merge.

Is there a simple way to do this? If not, could I request the -i, --info-rules argument from bcftools merge is added to bcftools concat to merge duplicates?

Many thanks,
Isaac
