Just to add to Helmut's very good response. It is important to note that SPM only provides the top 3 peaks in their tables. In my opinion, this is fine for a table in the text of the paper, but the complete list of peaks should be provided in the supplemental tables. The complete list of peaks can be obtained from my peak_nii program and is available on the nitrc website. You should only report voxels or clusters that are corrected for multiple comparisons. Thus, you want to set the cluster extent to something that only leads to significant corrected clusters (FDR/FWE), rather than 10. Best Regards, Donald McLaren ================= D.G.
