Hi there,

I am attempting to use PLINK2 with its --extract flag to extract the specific set of variants from UK Biobank dataset in *.bgen format. Unfortunately, the variant IDs contained in .bgen file is in rs_id format, which is not unique.

For example, the two different SNPs happening in the same locus will be given the exactly the same rs_id. But I only want to extract the information for one of them.

I wonder if there is a way to ask PLINK2 to extract the variants not only based on the variant ID but also by the Allele1 and Allele2 information?

Many thanks,

If you don't care about the rsIDs, you can just create new IDs with e.g. --set-all-var-ids.
