Yes, they have non-overlapping variants, that will be singletons and which we definitely want to preserve.

In terms of info field, my main interest is combining into a single VCF to be able to do variant QC, so I’d like to maintain the GQ, DP - but I think that’s calculated from the entries right?

Here is the description of one sample specific VCF
