Thanks. Really I was not sure it was a bug. Perhaps related to mol2
files, as it also happens with the aromatic rings of those I am
working on (while pdb files are read correctly).

The problem is that some bonds (actually all the ring bonds whether aromatic or not, except one) are not being read correctly from the sustiva.mol2 file, and instead pseudobonds are created. I don't know exactly what is causing the problem but I will report it.
