25.2.4.5.1. Identifying and restraining symmetry-related contacts (1982)

Without a search for symmetry-related bad contacts, it was quite common to build atoms into the same density from two different sides of the molecule. A number of models in the PDB contain these types of errors because neither the refinement nor the graphics programs available at that time would indicate this type of error.
