This node calculates the cardinality of a fingerprint.

For binary (BitVector) fingerprints, this is the number of set bits.

For count (ByteVector) fingerprints, this is the number of bits with a non-zero count.

This node was developed by Vernalis Research. For feedback and more information, please contact
