Symmetry

This node calculates the partition of heavy atoms in a CDK molecule into equivalent classes. The definition of equivalent classes is purely topological and the algorithm is derived from the algorithm by Hu, C.Y. and Xu, L., Algorithm for computer perception of topological symmetry, Analytical Chimica Acta, 1994, 295:127.

The node processes connected molecules only.
