A python library to work with molecules. Built on top of RDKit.
Project description
Molecular Manipulation Made Easy
Datamol is a python library to work with molecules. It's a layer built on top of RDKit and aims to be as light as possible.
- 🐍 Simple pythonic API
- ⚗️ RDKit first: all you manipulate are
rdkit.Chem.Molobjects. - ✅ Manipulating molecules often rely on many options; Datamol provides good defaults by design.
- 🧠 Performance matters: built-in efficient parallelization when possible with optional progress bar.
- 🕹️ Modern IO: out-of-the-box support for remote paths using
fsspecto read and write multiple formats (sdf, xlsx, csv, etc).

Installation
Use conda:
mamba install -c conda-forge datamol
Quick API Tour
import datamol as dm
# Common functions
mol = dm.to_mol("O=C(C)Oc1ccccc1C(=O)O", sanitize=True)
fp = dm.to_fp(mol)
selfies = dm.to_selfies(mol)
inchi = dm.to_inchi(mol)
# Standardize and sanitize
mol = dm.to_mol("O=C(C)Oc1ccccc1C(=O)O")
mol = dm.fix_mol(mol)
mol = dm.sanitize_mol(mol)
mol = dm.standardize_mol(mol)
# Dataframe manipulation
df = dm.data.freesolv()
mols = dm.from_df(df)
# 2D viz
legends = [dm.to_smiles(mol) for mol in mols[:10]]
dm.viz.to_image(mols[:10], legends=legends)
# Generate conformers
smiles = "O=C(C)Oc1ccccc1C(=O)O"
mol = dm.to_mol(smiles)
mol_with_conformers = dm.conformers.generate(mol)
# 3D viz (using nglview)
dm.viz.conformers(mol, n_confs=10)
# Compute SASA from conformers
sasa = dm.conformers.sasa(mol_with_conformers)
# Easy IO
mols = dm.read_sdf("s3://my-awesome-data-lake/smiles.sdf", as_df=False)
dm.to_sdf(mols, "gs://data-bucket/smiles.sdf")

Compatibilities
Version compatibilities are an essential topic for production-software stacks. We are cautious about documenting compatibility between datamol, python and rdkit.
See below the associated versions of Python and RDKit, for which a minor version of Datamol has been tested during its whole lifecycle.

CI Status
The CI run tests and perform code quality checks for the following combinations:
- The three major platforms: Windows, OSX and Linux.
- The two latest Python versions.
- The two latest RDKit versions.
