MolVS 0.0.5

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'

Installation

To install MolVS, simply run:

pip install molvs

Alternatively, try one of the other installation options.
