[Rdkit-discuss] Replace matched patterns with wildcards

2023-12-21 Thread Marawan Hussien via Rdkit-discuss
Hi, I am trying to use rdkit to replace matched SMARTS patterns in a molecule with a wildcard (*), and return a SMARTS string where the original molecule is an instance of this returned SMARTS string, I tried the following:from rdkit import Chem def generate_modified_smarts(smiles,

Hello,I am trying to perform a pharmacophore similarity search using the RDKit implementation of the Pharmacophore fingerprint code.While reading the documentation, I came across this sentence:"In the RDKit scheme the bit ids in pharmacophore fingerprints are not hashed:"Does this mean each bit

[Rdkit-discuss] appending new rows in dataframe with stereo-isomers

2020-08-29 Thread Marawan Hussien via Rdkit-discuss
Hi, I am trying to append (update) a pandas dataframe (created by Pnadatools from a CSV file) with potential stereoisomers for each molecule in the dataframe.My understanding is that the EnumerateStereoisomers function returns a generator that I can loop through and use the mol object (or
