Hi Lucina, Assuming the 7EVs do not include rest, yes those contrasts are correct. Each of them will results in a t-test comparing the mean activity in the various conditions to rest. For instance, in your rest - 7 EVs, you'll find regions where the mean activation across all 7 EVs decreases relative to rest. Obviously any one condition may show a different pattern in that same region though Joe -------------------- Joseph T. Devlin, Ph. D.
