Hi Greg, I have been trying to percieve the chemo features from a Mol object, so I guess MolChemicalFeatureFactory is what I supposed to use, right? I see that the method like "MolChemicalFeatureFactory.GetFeatureFamilies" requires a mandatory argument of "MolChemicalFeatureFactory instance". But the "__self__" method in MolChemicalFeatureFactory forbid to get a instance from python. So how should I use "MolChemicalFeatureFactory.GetFeatureFamilies" appropriately?
Have a nice day, -- Yours sincerely, Xiaofeng Liu ------------------------------------ Drug Discovery and Design Center, Shanghai Institute of Materia Medica, Chinese Academy of Sciences P.R.China
