[ccp4bb] O-glycosylation in ccp4/refmac

2008-02-28 Thread Rebecca Phillips
Hello, I am trying to model an O-glycosylation modification at a threonine, but this seems to be problematic when I try to refine the model in refmac. The run fails, and the log says that a new ligand was found (the sugar). It offers a lib.cif file to add to the library and try the
