Path fingerprints that are generated from a structure where atoms are described by atomic number and aromaticity; bonds are described as single, double, triple, or aromatic; and the results are hashed into a bit string of fixed length.
Note: Although these fingerprints were originally described by Daylight CIS, many other investigators have also implemented them.
