WebJan 30, 2024 · Here we just drop the rings argument to getSharedRings (), it will use all of the molecule’s rings: matches = list(getSharedRings (mol, [Chem.MolFromSmarts (sma) for sma in (' [*]-Cl',' [*]-Br')])) print(matches) drawMolWithRings (mol,matches) [ {0, 1, 3, 4, 6, 7}, {15, 16, 17, 18, 19, 21}] We can also find any rings that have a Cl, but not a Br: WebThe RDKit can generate conformations for molecules using two different methods. The original method used distance geometry. [1] The algorithm followed is: The molecule’s distance bounds matrix is calculated based on the connection table and a set of rules. The bounds matrix is smoothed using a triangle-bounds smoothing algorithm.

This document contains many potentially useful example SMARTS which may be used to perform searches. templates, examples and ideas. These SMARTS have been tested, but they may still contain errors.
WebThis software finds the maximum common substructure of a set of structures and reports it as a SMARTS string. The SMARTS string depends on the desired match properties. For example, if ring atoms are only allowed to match ring atoms then an aliphatic ring carbon in the query is converted to the SMARTS " [C;R]", http://www.mayachemtools.org/docs/scripts/html/RDKitSearchFunctionalGroups.html
