Dear Yang Li, you probably can download your library file (CIF) from the Hic-up website: http://xray.bmc.uu.se/hicup/ Infact an heterocompound named "abc" is already existing there... that's a "modified acarbose hexasaccharide". Is that the one you were looking for? In this case, here it is: http://ligand-depot.rutgers.edu/pub/ABC/ABC.cif.html
Or you can try to let refmac write one for you thanks to a refinement although this one will probably not be an idealised ligand because derived from what's in your structure. But you still will be able to modify it later. Hope this helped, Virgile Quoting yang li <[EMAIL PROTECTED]>: > Hi All, > If I have a pdb with some residues named "abc" in it, coot can read > it and display it well, > but I cannot do real space refine to such residues.
