No, "gap link" is a misnomer: it means in fact that refmac it's treating
the amino acids boundaries involved effectively as a gap, that is, as if
you would be expecting amino acids to lay in between.
Refmac5 must be assuming that you number your protein according to your
protein sequence, which is continuous. In my opinion, this is
reasonable. Instead, it should the longer sequences with respect to
which you would like to have yours numbered that should have insertion
codes (supported by refmac5). Unless you have deleted those particular
amino acid residues from your native sequence for some reason...
In any case, to solve your problem, I don't know if there is something
like a "nogap link" notation in refmac5...
Cheers,
Miguel
