I don't expect them to appear exactly at the right place. I am using functional localizer technique and I know in advance where more or less my region should appear. Specifically, fusiform gyrus can't appear in frontal lobe. The less preprocessing we do the better, so I prefer not to make normalization when I can localize my ROIs without it.
