The molecule’s distance bounds matrix is calculated based on the connection table and a set of rules. The original method used distance geometry. The RDKit can generate conformers for molecules using two different
GenerateDepictionMatching3DStructure in AllChem.py for an example of 2DCoordsMimicDistmat(), but that isīeyond the scope of this document. More fine-grained control can be obtained using the core function Here is an illustration of the results using the ligand from PDB structure 1XP0: This is available using the function 3DStructure(). Running this process for the molecules above gives:Īnother option for Compute2DCoords allows you to generate 2D depictions for molecules that closely mimic 3D conformers. GenerateDepictionMatching2DStructure ( m, template ) Compute2DCoords ( template ) 0 > ms = > for m in ms.

The majority of the basic molecular functionality is found in module rdkit.Chem: Reading, Drawing, and Writing Molecules ¶ Reading single molecules ¶ Contributing to the documentation is a great serviceīoth to the RDKit community and to your future self.

This document is intended to provide an overview of how one can use If you need to continue using Python 2, please stick with a release from the 2018.09 Getting Started with the RDKit in Python ¶ Important note ¶īeginning with the 2019.03 release, the RDKit is no longer supporting Python 2.
