I need to replicate some results that were calculated on version 4.0.3 and I'm having some issues. Hopefully someone is around that worked with the software back in the early 2000's! I'm using the majorms plugin to predict the major microspecies from smiles inputs. I've moved from using the existing software (which worked great) to the 4.0.3 version which aromatizes the smiles by default. Dearomatization of the output isn't acceptable because I need the identical structure as an output (apart from the ionisation changes). Is there a way to maintain the input kekule structure with this plugin?
