22. 2D frequency fingerprints

• Definition

  2D frequency fingerprint descriptors calculate the frequency if there is a relevant bond but calculate it to be zero(0) if there is not. Here, the fingerprints are binary vectors that indicate "1" if each bit has a specific substructural fragment in the molecule, and "0" if not.
