Rapid and Accurate Conformer Ensemble with RDKit for Transition States

Rapid and Accurate Conformer Ensembles with RDKit for Transition States

Installation

$ pip install racerts

Usage

racerTS can be imported as a Python module that is easily integrated into workflows for transition state conformer ensemble generation. For further information, see the separate documentation.

>>> from racerts import ConformerGenerator
>>> cg = ConformerGenerator()
>>> ts_conformers_mol = cg.generate_conformers(file_name="example.xyz", charge=0, reacting_atoms=[2,3,4])
>>> cg.write_xyz("ensemble.xyz")

It can also be accessed via a command line interface.

$ racerts example.xyz --charge 0 --reacting_atoms 2 3 4
