getTanimoto

public static double getTanimoto(byte[] bitstring1,
                                 byte[] bitstring2)

Calculates the Tanimoto coefficient of the two bit strings. The calculated value is between 0 and 1. The higher the value the more similar are the bit strings. All bits in the byte arrays are used. The length of the byte arrays has to be equal.

getTanimoto

public static double getTanimoto(byte[] bitstring1,
                                 byte[] bitstring2,
                                 int bytesToCompare)

Calculates the Tanimoto coefficient of the two bit strings. The calculated value is between 0 and 1. The higher the value the more similar are the bit strings.

Parameters:

bytesToCompare - the number of bytes to use in the calculcation.

Since:

JChem 3.1
