Molecule Validation and Standardization
MolVS is a molecule validation and standardization tool, written in Python using the RDKit chemistry framework.
Building a collection of chemical structures from different sources can be difficult due to differing representations, drawing conventions and mistakes. MolVS can standardize chemical structures to improve data quality, help with de-duplication and identify relationships between molecules.
There are sensible defaults that make it easy to get started:
>>> from molvs import standardize_smiles >>> standardize_smiles('[Na]OC(=O)c1ccc(C[S+2]([O-])([O-]))cc1') '[Na+].O=C([O-])c1ccc(CS(=O)=O)cc1'
To install MolVS, simply run:
pip install molvs
Alternatively, try one of the other installation options.
