Relevant to this discussion, the 2018 ACA meeting in Toronto will have a session on "Best practices for building, refining, and analyzing ligands in macromolecular structures” co-chaired by Anna Gardberg and Kurt Krause. I expect this session will include case studies of structures that went wrong as a way of educating the community about the potential pitfalls of building ligands into electron density. John J.

Their work is based on a deposited structure – by other authors - that is incorrectly interpreted. Is there a process for removing a demonstrably wrong structure (deposited by others) from the PDB and replacing it with a correctly interpreted structure based on the original data? Or is there an alternative, and generally recognized, way of getting the correct structure in the public domain? Many thanks for your advice on this matter.
