Dear folks: I am currently using Phenix to refine a structure that has many carbohydrate chains on it. I created the cif file according to an old message from Dr.Ralf W like the following: refinement.pdb_interpretation { apply_cif_link { data_link = NAG-ASN residue_selection_1 = chain A and resname NAG and resid 900 residue_selection_2 = chain A and resname ASN and resid 329 } apply_cif_link { data_link = NAG-NAG-b-D residue_selection_1 = chain A and resname NAG and resid 901 residue_selection_2 = chain A and resname NAG and resid 900 } apply_cif_link { data_link = NAG-MAN-b-D residue_selection_1 = chain A and resname MAN and resid 902 residue_selection_2 = chain A and resname NAG and resid 901 }
} However, there was an error: Missing CIF link : data_link_NAG-NAG-b-D please check for spelling errors or specify the file name with the link as an additional argument. How can I fix this problem? Thanks a lot and have a nice holiday season.
