[Rdkit-discuss] Volume Overlap using RDKit

2013-01-22 Thread JP
RDKitters, Long time no type, I've been busy with that little chestnut of my PhD... I would like to align two molecules and calculate the shape tanimoto with ShapeTanimotoDist(...). The issue is that this method requires a pre-defined alignment - which I do not have. Is there a way how to do a

Thanks Niko, Taka for your prompt replies. My molecules are not guaranteed to have some common substructure, so an RMSD align is out of the question. I [think I] want a 3D alignment which maximizes volume overlap between the two molecules. - Jean-Paul Ebejer Early Stage Researcher On 22

Hi JP, Do you want to do a shape align or just any sort of alignment? There is a MolAlign in All.Chem which will give you an RMSD align. This works well if you have reasonably similar molecules (do a GetSubstructMatch before to get the atom list). Don't think there is a shape alignment for

If you're just looking for 6 membered rings, you can define a SMARTS that matches 6 membered rings like this *1~*~*~*~*~*1. You can also use this approach to identify all rings (at least those within reason). You can use an expression like this [*1+string.join([*~]*x,)+*1 for x in range(1,19)]
