Hi - I think I can probably figure this out by re-reading the 3dDeconvolve manual, but I thought I'd ask anyway. I have reduced each subject using 3dDeconvolve with BLOCK (for event-related data) for let's say 6 different conditions. The output for each subject includes a test of the coefficient for each condition that I then take to an ANOVA. Does this coefficent (beta) test whether the fit for any subject/condition is different than ZERO or different than the BASELINE? thanks, mb
