Automated Matched Pairs

This node detects and outputs all the possible matched molecular pairs in a data set and returns the pairs, along with the corresponding (single-point) chemical transformations and property changes. Requires the RDKit nodes.

Because it is not based on MCS detection, the algorithm comparatively fast and efficient. More details can be found here:
