Jake, Click save when viewing the results. Open up imcalc, select the contrast you saved. Use the equation i1>0. Then you will have your mask. Then you can choose mask with image when viewing the results. Remember that the corrected statistics (e.g. FWE and FDR are still based on the whole brain. To get the corrected results for your mask, you need to click the SVC button as well. Best Regards, Donald McLaren ================= D.G.
