Doug, Actually my input is not the difference map, but the separate time points (it's timepoint 2 weighted with -1 and timepoint 1 weighted with 1, described in the matrix file I sent you). So in order to determine whether there's thickening or thinning in the controls and training subjects, would I still need to use the additional contrasts [1 0 0 ....] and [0 1 0 ....]? Thank you.
