Dear all, I have fit my ligand into its density with coot. Then, I add the ligand into the protein's pdb and try to do refine with refmac5. First, the error comes, error message Refmac_5.5.0109: New ligand has been encountered. Stopping now
The next time, I input the .cif file generated by the first run of refmac5 and rerun the program. And the error comes as, ERROR : atom :04 5CD 225 XX is absent in the library ATTENTION: atom:4__0 5CD 225 XX is missing in the structure ERROR : atom :04 5CD 224 Bb is absent in the library ATTENTION: atom:4__0 5CD 224 Bb is missing in the structure Number of chains : 7 Total number of monomers : 750 Number of atoms : 3691 Number of missing atoms : 2 Number of rebuilt atoms : 0 Number of unknown atoms : 2 Number of deleted atoms : 0 Number of bonds restraints : 3452 Number of angles restraints : 4672 Number of torsions restraints : 2372 Number of chiralities : 512 Number of planar groups : 612 IERR = 1 There is error. See above ===> Error: Fatal error. Cannot continue Refmac_5.5.0109: Fatal error. Cannot continue Times: User: 13.8s System: 0.1s Elapsed: 0:14 Could anybody please help me to solve this problem?
