/* ERROR/WARNING messages:

E: 1-3 bond count is inconsistent

An inconsistency was detected when computing the number of 1-3
neighbors for each atom.  This likely means something is wrong with
the bond topologies you have defined.

E: 1-4 bond count is inconsistent

An inconsistency was detected when computing the number of 1-4
neighbors for each atom.  This likely means something is wrong with
the bond topologies you have defined.
