Light adapter classes around Open Babel, RDKit, and ChemAxon for the functionality needed in eQulibrator.
Install
Please note that while equilibrator-cheminfo as a pure Python package is operating system independent, the same is not true for the cheminformatics backends Open Babel, RDkit, or ChemAxon. While both Open Babel and RDKit nowadays provide Python wheels, we do not test them on all platforms.
RDKit
pip install equilibrator-cheminfo[rdkit]or
Open Babel
pip install equilibrator-cheminfo[openbabel]ChemAxon
If you wish to use ChemAxon, you need to install the software, acquire a license, and set the environment variable CHEMAXON_HOME.
pip install equilibrator-cheminfo[chemaxon]Usage
The main feature in this package is a uniform class interface to molecules from Open Babel, RDKit, or ChemAxon. The interface is defined by the equilibrator_cheminfo.AbstractMolecule abstract class that the three concrete classes adhere to.
from equilibrator_cheminfo.chemaxon import ChemAxonMolecule
from equilibrator_cheminfo.rdkit import RDKitMolecule
from equilibrator_cheminfo.openbabel import OpenBabelMoleculeSome of the supported methods are:
mol = OpenBabelMolecule.from_smiles("CC=O")
mol.get_charge() # 0
mol.get_molecular_formula() # 'C2H4O'
mol.get_molecular_mass() # 44.05
mol.get_inchi_key() # 'IKHGUXGNUITLKF-UHFFFAOYSA-N'You can also always access the cheminformatics backend object directly and pass it as an argument to functions directly imported from there.
mol.native # <openbabel.pybel.Molecule at 0x7f2a14b36c70>
mol.native.calcfp().bits # [330, 624, 671]If there are general methods that you think are missing from the abstract interface, please say so in an issue.
