Aromatic Amines [message #890]

I was wondering how DW calculates 'Aromatic Amines' property.
In the attached file, top structures shows 4 Aromatic amines, that I understand.
However, the bottom structure mentions only 2. I thought it should be 3.

Thank you for pointing this out. You are, of course, right that the number of aromatic amine atoms should be three.
I have checked the source code and atom 1 was not counted as amine, because it has a negative neighbour.
In this case one could even argue that the nitrogen has no basicity left, but finally it is an amine even if not basic.
I have changed the logic of the source code. It will be fixed in the next updates.
