Where:
- imol_ligand is an integer number
- chain_id_ligand is a string
- resno_ligand is an integer number
- ins_code_ligand is a string
- imol_reference is an integer number
- chain_id_reference is a string
- resno_reference is an integer number
- ins_code_reference is a string
Overlap residue with "template"-based matching.
Overlap the first residue in imol_ligand onto the residue specified by the reference parameters. Use graph matching, not atom names.
Match ligand atom names By using graph matching, make the names of the atoms of the given ligand/residue match those of the reference residue/ligand as closely as possible - where there would be a atom name clash, invent a new atom name.
Returns: success status, False = failed to find residue in either imol_ligand or imo_ref. If success, return the RT operator.
