Dear Coot and CCP4 users,I need to add a glycosylated Asn in my protein. To do it, I copied from an existing PDB file where it has 2 NAG and 1 BMA, and modeled it to the density in Coot. Then I wrote out the PDB.
WHen I refined the structure again with refmac, an error occured, "Error: atom: NAG 1 CC is absent in the library"
Im not sure where I should look, but tried to edit the cif file on the bonding, but just could not get it to work.
Hope to get your help. Thanks! Jie yang
