Renaming rsid column after split


What would be the best way to rename the rsid column with something like Chr:Pos:Ref:Alt_hg38 after applying the split multi-allelic function?

Thank you for all your help.

Hi @sk4919 !

Does this do what you want?

mt = mt.annotate_rows(
    rsid = hl.format(
        "%s:%d:%s:%s",,, mt.alleles[0], mt.alleles[mt.a_index]

Thank you, good sir!
