Dear SPM'ers, I have a query regarding the p-values of my activations. If both the P(n>K)uncorrected and corrected values are significant but the voxel P(t>u) corrected values are not significant within the cluster, can I still be confident in stating the cluster is indeed significant despite the voxel p-values (corrected). If the cluster P-values are significant but the voxel P-values (corrected)are not, what exactly does this mean? Can anybody help.
