Hi Gurus,
In response to the recent foofaraw about cluster size thresholds, I want to estimate smoothness from my group-level residuals to see if I get drastically different results. Is there an easy way to do this? My current plan involves 3dcalc, but the glts that I used aren't orthogonal, so I have to think about whether I'm using the right parameters (good!) or the dual to the right parameters (garbage!) and that question always makes my head hurt.
