Unsupervised Data Base Clustering Based on Daylight’s …

There are two distinct types of fingerprints which the Daylight systemprovides for reaction processing. First is the "normal" structuralfingerprint, which is useful as a superstructure search screen. Second is the"difference" fingerprint, which is useful as a metric for the bondchanges which occur during a reaction.
