Rdkit ring count
Did you know?
WebRDKit uses an atom-based pi-electron counting algorithm to check aromaticity based on Huckel’s Rule. Therefore, this method identifies “true” aromaticity, rather than simply the RMG bond type. The method currently restricts aromaticity to six-membered carbon-only rings. This is a limitation imposed by RMG, and not by RDKit. WebFeb 28, 2024 · So, in RDKit, if you convert smiles_1a to mol and this mol back to SMILES again, you get c1ccc2c (c1)-c1cccc3cccc-2c13. If you search with this, you will still not find structures 3 and 5. Probably because of the defined single bonds. However, if you replace - by ~, you get smiles_1b: c1ccc2c (c1)~c1cccc3cccc~2c13.

http://rdkit.org/docs/RDKit_Book.html WebMar 1, 2024 · In RdKit, the method SetProp is used to set an atomic property for the atoms involved in the molecule. This method takes two arguments: the peroperty to set and its value. The idea is simple: Create an rdkit mol object from SMILES string, iterate over the atoms, and set the desired property to a custom value.
WebDec 24, 2024 · R0 matches an atom in a ring with size 0 (i.e., not a ring atom) D1 matches an atom with explicitly one bond (so !D1 matches atoms with more than one bond).
