Thank you very much for your answer.
Yes, I would like to treat those zeros as NaN if that is possible? Or is there a way of masking them out with the subrange option or something?

Thanks again.

EDIT:
I have also been wondering about the output of non-integer numbers for the index sub-brik of both 3dKruskalWallis and 3dFriedmann. In the first volume I should see the index of the -dset that was significantly different, while the second simply shows the statistic. However in the first sub-brik I see stuff like .9999 and so on, but I also see some integer values.
So is it safe to simply convert these double values to integer numbers and infer that they mean the index?
