Thanks - sorry I should have searched the archives first. As a suggestion, could you alter the warning text to include the fix decription (i.e. "include this in your .coot.py)? This way users would know what to do right away. On Tue, Jan 31, 2017 at 2:51 PM, Paul Emsley

This is an occurrence of microheterogeneity and it is not all that uncommon. See Crambin as a classic prototype. Coot should be able to handle this. The work-around you suggest creates a very different model. Residue 93A lies between 93 and 94 so you are actually inserting an entire
