Dear AFNI experts,

I am looking to use the 3dKruskalWallis function for the comparisons of 5 different pipelines, could you please verify if this call is correct, if I would like to exclude any zero voxels in the comparison?

My data consists of 8 sub-briks for each of the five pipelines. I want to avoid that positive valued voxels are compared to zero valued voxels.

Thanks a bunch.
Best,
Barbara
