  1. Listed are the currently available molecular fingerprint in CDK with information about whether they come as a bit and/or count version, what CDK version they were introduced in, their default size, and relevant references, where applicable
  2. * For the CircularFingerprinter the bit version is folded to 1024 whereas the count version is unfolded
  3. \(^\dagger\) The LingoFingerprinter does not have a default size
