Hi Susan, There isn't currently a function available to calculate Tversky distance using shapes (though it wouldn't be terribly difficult to add), but you can use the ShapeProtrudeDist to generate a measure for comparing two molecules of unequal size. Here's a simple demonstration: In [3]: m = Ch

Dear all, I would like to compute the shape overlap between two molecules. I understand that there is rdShapeHelpers.ShapeTanimotoDist however I would like to compare the two molecules in a tversky manner. For example I have mol1 and mol2 and I want a score which penalises mol1 for failing to
