Dear Oarabile, As Paul said, without any details it is hard to figure out what might be going on. Where did the cacodylate come from? Was it present in the starting pdb, did you create it yourself, or did you import it in Coot with the get monomer option? If you did not use the get monomer option, that would be the first thing to try. Delete the cacodylate present and use get monomer. That way you are sure that the nomenclature of the atoms is correct and that the cif file for cacodylate is loaded. Without cif file, the structure will explode, but in this case I would expect that Coot would not refine and produce an error message.

The molecule breaks apart and some of its components attach to the peptide residues. Due to this, phenix.refine would not accept this as the input for refinement. Is there a way I can make cacodylate ion stay in its electron density and refine my structure with cacodylate ion? I appreciate your help! Best Regards, Oarabile M.
