Dear Friends, I have Zn atoms in my pdb file. So, I think I need to run elbow to create the cif otherwise refinement stops. I did the following and got the error as follows: phenix.elbow generate_easy_r4.pdb --do-all ------------------------------------------------------------------------------ electronic Ligand Builder & Optimisation Workbench (eLBOW) 1.4 3 - Nigel W. Moriarty ([email protected]) ------------------------------------------------------------------------------ Random number seed: 664322001 0:00 Parsing Parsing Parsing Parsing Parsing Parsing Parsing Parsing Parsing P No molecule read Use --all-residues to view residues if this is a PDB file Can anyone suggests at this point, what I should do? Thanking you in advance... Raja
