Hi all,
I've successfully run 3dMVM on a dataset to do second level analyses. Do you have any suggestions as to what I should use to do cluster correction? I've used -clustsim in for t-tests, but that is not part of 3dMVM. I'm also not certain how to come up with a smoothing factor if that is required. I used a smoothing kernel of 4mm on my data, but I know it's the smoothness of the residuals that matters. I did output an errts datasets for each case. My guess is I use 3dClustSim, but I'm not sure how to use it or how to apply it to the dataset I've obtained.

I also was curious how to apply ETAC or ACF options to this analysis.
Thanks!
Matt
