This is the minimum length of a word which shall be considered as element of the signature. Should be either 2 or 3.

The quantRate is a measurement for the number of words that take part in a signature computation. The higher the number, the less
words are used for the signature.
For minTokenLen = 2 the quantRate value should not be below 0.24; for minTokenLen = 3 the quantRate value must be not below 0.5.
