To obtain canonical SMILES the atoms in a given molecule have to be uniquely and consistently numbered. In the case of RDKit this is done by using a modified version of the Morgan algorithm [27, 28].The SMILES generation algorithm is then able to traverse the molecular graph always in the same way (Fig. 1a). …

WebJul 1, 2024 · RDKit requires 2 things to create a complete molecule from scratch: Elements (either the symbol of the atom, or the atomic number). This will allow us to create atoms which will also store all the extra information regarding residues, atom names and types, temperature factors…etc.

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. WebSep 1, 2024 · The RDKit implementation picks the atom with the smallest Morgan invariant. This way the choice is independent of the atom order in the molecule. In the case of symmetric atoms a and/or d, the RDKit implementation stores all possible torsional angles in the TF instead of only storing the smallest one as in the original approach.
