Ok, now I understand.
Thanks a lot Mark. Just one think, I feel more clear the 3D
representation for the results. If I'm not wrong, that option is not
available when using volumetric output (.nii) plus randomise, is not it?
In case I would rather prefer the 3D representation, then I should
assume that results are FDR corrected as the most. Am I wrong?
thanks again,
Best
