Hi-

Note that the cluster maps themselves are identical, as given by the 3dDiff command above, which is good.

The only values in the table that appear to differ relate to using the values themselves; most/all of these would be expected to be different:
+

CM values use the absolute value of the voxel values as weights.

... so any of the CM columns will likely differ.
+ the Mean, SEM and Max Int values will necessarily differ (because those are different datasets).
+ "MI RL" is this:

MI RL        : Coordinate of the Maximum Intensity value in the
                    Right-Left direction of the volume cluster

So, these differing means that the location of the 'peak intensity' in the F-stat and in the t-stat differs. I am slightly surprised by that, actually, and perhaps Gang can weigh in if that makes sense.
