[phenixbb] O-linked glycosylation refinement in Phenix

Dear all,

I'm refining a structure which has both N-linked and O-linked
glycosylation. I use Phenix to do the refinement. It works well for the
N-linked NAG. I defined the link as the following:

    apply_cif_link {
      data_link = "NAG-ASN"
      residue_selection_1 = "chain A and resname NAG and resid 701"
      residue_selection_2 = "chain A and resname ASN and resid 518"
    }

But it doesn't work when I defined the fucose-threonine link as the
similar way:

    apply_cif_link {
      data_link = "FUC-THR"
      residue_selection_1 = "chain A and resname FUC and resid 801"
      residue_selection_2 = "chain A and resname THR and resid 596"
    }

The error message is "missing CIF link: data_link_FUC-THR".

Does anyone have the cif link file of FUC-THR?

Thanks a lot!
