Since multiple intermediate steps in scaffold dissection rely on aromaticity information of specific substructures, an initial aromaticity detection is applied at the primary scaffold generation. And again at the end of a scaffold dissection process, a final aromaticity detection is applied to all generated parent scaffolds to make sure that the aromaticity information stored on the scaffold objects is in agreement with the returned structures. This last step might lead to cases where the same ring is not detected as aromatic in a smaller parent scaffold but in the bigger child scaffold in which it is a substructure. This is due to the cycle finder algorithms usually employed for aromaticity detection that are not SSSR-/MCB-based but also take cycles into account that span multiple rings of the molecule. It should be interpreted in the way that the ring in the parent scaffold gained aromaticity in the child scaffold through combination with other rings.
