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
