You can set the cut-off to whatever you like. This kind of analyses
allways carry a certain amount of randomness. In the best case you
should show that your results are not dependent on this kind of choices.
We are working on different algorithms that avoid this kind of cut-offs,
by e.g. using autocorrelation functions.
