Setting [MINIMUM LENGTH] parameter smaller than 32 will cause an exception

[Fischer-Bjoern]

This error occurs because there is an array paaTest that is being populated which uses a fixed size of 32 entries.
When the window is smaller than 32 entries, populating this paaTest will result in access to an element which is beyond the end of the loaded window and it will thus cause an exception.

Here is the example output:

I do not yet fully understand the purpose of paaTest so I don't know how to fix this myself.

My purpose for setting a very small window size is that I want to use HIME to try and analyse a time series for the presence of Motivs of varying sizes, some of these Motivs might be quite short.
