[Rdkit-discuss] Making Morgan Fingerprints more SMILES-like

2020-01-09 Thread Kramer, Christian via Rdkit-discuss
Dear RDKit community, Happy new year! I am looking for a way to make the circular Morgen Fingerprints more SMILES like. The background is that with the default definition of atom invariants in the RDKit implementation, Morgan Fingerprints do not explicitly take into account aromaticity, and use

[Rdkit-discuss] MMPDB V2.2 update

2019-02-05 Thread Kramer, Christian
Dear RDKitters, To those of you who are interested in Matched Pairs analysis: mmpdb, a library for doing large-scale MMP analysis, has been updated to version 2.2. This update introduces three new features that enable reducing the size of the database created. These are:

Re: [Rdkit-discuss] RDKIT 2018.3 and MMPDB problem

2018-05-09 Thread Kramer, Christian
Dear all, Andrew's fix for the wildcard atom representation in RDKit 2018.3 has just been incorporated into the main mmpdb branch. If you download the latest version of mmpdb, it should now work with with the current version and also with previous RDKit versions. Note that you have to rebuild

Re: [Rdkit-discuss] sanifix

Hi Mei, I do not have an answer to your question about sanifix4.py, but with your test molecule I do not get a "Can't kekulize mol" problem when reading/writing it with RDKit. Standard RDKit seems to be doing its job: In [1]: import rdkit In [2]: from rdkit import Chem In [3]: mol =

Re: [Rdkit-discuss] mmpdb installation on windows using mingw

2017-09-22 Thread Kramer, Christian
Hi Markus, thanks for pointing this out. The reason for that error message is that signal.SIGPIPE is not available under windows. This seems to have slipped below our radar, since we developed the code on Linux. There is a simple solution to this: In the mmpdb file, one needs to import os and

[Rdkit-discuss] mmpdb 2.0 - a package for MMP database generation and analysis

[Rdkit-discuss] Chirality conservation during atom replacement

2016-06-21 Thread Kramer, Christian
Hi RDKitters, I am having trouble with chirality conservation during fragmentation of molecules. Is there a simple way of preserving chirality during splits on chiral atoms? Am I missing a simple function? Andrew has brought this topic has come up on the mailing list before, but so far there has
