Fingerprint Toolkit Supporting fingerprint creation and customization The Fingerprint Toolkit is a programming library which provides a comprehensive programmatic interface to Daylight's fingerprinting and similarity algorithms. In addition, the toolkit provides control over the fingerprinting algorithm, including folding, bit-manipulation, and similarity comparisons. This toolkit can also be used to implement custom fingerprinting and similarity algorithms. Objects supported by this Toolkit include: Fingerprint - object representing a fingerprint This Toolkit can be used to: Allocate and create new fingerprint Fingerprint molecule and reaction objects Specify size and folding parameters for a fingerprint Manipulate fingerprints in a bitwise fashion Directly access 15 named similarity metrics (e.g., Tanimoto, Euclidean, and Tversky similarity functions) Create new similarity metrics with mathematical expressions Create mixture fingerprints for large libraries
