Hi Donna, This reminds me of the reviewer comment I once got that block designs were obsolete since event-related designs were now possible. Nonsense of course. Given i) the widespread use of affine transformations, ii) the fact that since they warp low-resolution functional data to a blurry average template, most studies aren't going to see any advantage in nonlinear transformations, I think the justification for continued use of affine transformations is at least as strong as for continued use of average template-based analysis of group data. Now, the argument can be (and has been) made that such average template methods are deeply flawed, but somehow I don't think it would be reasonable for such techniques to be banished overnight. Just my 5p. -Tom On Feb 4, 2008 3:48 PM, Donna Dierker <[log in to unmask]> wrote: > Steve and FSL users, > > I apologize for the fuss and confusion.
