I just performed an analysis with and without nonisotropic correction; however, I am confused as to how to interpret the corrected cluster sizes. I am using SPM5.Update1782.
For example, uncorrected size of a cluster is 5000 voxels and the corrected cluster size is 8000 voxels (as displayed whole-brain statistics table under Ke). If I click the eigenvariate button and specify VOI as the cluster, it reports 5000 voxels in the cluster in the image.
(1) What should 8000 voxels be interpreted as?
(2) How should it be reported in a paper?
