^{a }Let P1 and P2 be two pharmacophore fingerprints, a be the count of bits which are set to 1 in both P1 and P2, b be the count of bits which are set to 1 in P1 but not in P2, c be the count of bits which are set to 1 in P2 but not in P1, and d be the count of bits which are set to 0 in both P1 and P2. So a is called the number of total matches, b and c are called the number of single matches, and d is called the number of no matches.
