[Rdkit-discuss] GPU Implementation of shape-based 3D overlap on rdkit?

2020-11-02 Thread Andy Jennings
Hi, I see that back in 2014 there was some discussion of using CUDA inside of RDKit and how it may be possible to produce a FastROCS-like open source alternative. I was curious if anyone had made such a breakthrough. Since GPU availability is now so common, and datasets are becoming so large, I

[Rdkit-discuss] Exhaustive Library Enumeration

2018-01-17 Thread Andy Jennings
Hi RDKitters, I have a question and an observation on the topic of library enumeration. First, the question: is there a call within RDKit to trigger the exhaustive reaction of reagents? For example, if I have two reagents - a primary amine and an akyl chloride - can I tell RDKit to enumerate the

[Rdkit-discuss] Behavior of ETKDG / EmbedMultipleConfs

2018-01-12 Thread Andy Jennings
Hi RDKitters, Whilst looking at generating some conformations of molecules using the ETKDG method with EmbedMultipleConfs I've come across some strange (to me) behavior. When I generate conformations of some molecules with the randomSeed as -1 the result is a variable number of conformations.

[Rdkit-discuss] Question regarding 3D pharmacophores

2017-10-20 Thread Andy Jennings
Hi, I'm curious if anyone has figured out a way to compare two molecules based upon their pharmacophore similarities. Specifically, I want to compare 2 molecules in their _absolute_ locations, and not simply see if they have 2 pharmacophores that match well via a translation/rotation. From what I

[Rdkit-discuss] Default behavior of certain calls

2017-10-12 Thread Andy Jennings
Hi, First off: great work on the RDKit - a great resource for those of us that like to cook up our own solutions to problems. The default behavior of certain calls (e.g. Chem.SDMolSupplier, Chem.MolToSmiles) has default behavior that is the opposite of what I would generally want. For instance I
