Dear All, I am using WinCoot 0.8.6.1 .
I find Coot fails every time when doing real space refinement of Iso-aspartic acid residue (IAS) in PDB entries containing IAS. For example, in PDB entry 1DY5 chain A residue 67th IAS, when doing real space refinement of this residue, Coot fails with error message "Refinement setup failure, Failed to find restraints for: IAS". To import the IAS cif file, I tried to get monomer in Coot File---> Get monomer.. , input IAS, but Coot fails with message "We don't have the entry for this. Shall I go and get it?" After I click ok, Coot fails with message "Failed to import molecule." As far as I tried, this problem occurs at other entries containing IAS in PDB (for example entry 1RTU chain A 45th IAS). I am asking if any of you have some suggestions of doing this. Thanks ahead. Best, Xiao
