A couple of quick questions:
(1) In the Fox et al paper, they used the residuals to do their correlations
after removing various effects. Is there any advantage or disadvantage to
using the residuals to do a straight correlation rather than using a larger
design matrix to do the analysis all at once and not dealing with the residuals?
(2) How can one save out the residuals of the entire time series in SPM5?
Thanks.
