Hi,

I'm trying to figure out how to do cluster correction on group data, and I'm confused by the admonition not to use 3dFWHMx on the output of 3dDeconvolve or 3dREMLfit. My inclination is to run 3dMEMA on my data, subtract the results from each beta map (i.e., subtract the estimate for the appropriate group), and then run 3dFWHMx on the residuals and feed the results to 3dClustSim. Is this what I'm being told not to do? If so, what's the right way to do this? I feel like this is a "dumb" question that I should have been able to answer by searching this board, but so far I haven't had any luck. Sorry if this has been asked and answered.

I'm also curious whether there are any problems with using 3dClustSim and 3dMEMA together (as opposed to 3dClustSim and 3dttest++), since the estimates are constructed in a different way and 3dClustSim doesn't take t-statistics into account. Should I worry about this?

Isaac

EDIT: Found an answer to the first question here.
