minor valence check error

Draw pyridine N1=CC=CC=C1. Draw N=O. Aromatize it. No valence error (correctly).





Now draw pyridine again. Aromatize it. Draw an N=O. Valence error (incorrectly).





The SMILES definitions of the two results are both O=[n]1ccccc1.





The behavior is the same in both Marvin 5.0 and 4.1.12.

Hi Bob!





Thank you for the warning.


We will check this.

Dear Bob,





Sorry for the late answer, I'm just back from holiday, but anyway the problem has been solved in Marvin 5.1.
