Hey folks,

I am planning to use 3dmvm to run an analysis on a bunch of beamformer volumes generated from MEG data. I'd like to use 3dclustsim to identify a minimum cluster size threshold, but I'm unsure about the best way to do that. Specifically, I have two questions:

1) Is it possible to output the residuals from my 3dMVM model, and if so, would it be appropriate to use these to estimate the smoothness of the of the data?

2) Would you recommend using a gaussian (-fwhm) or a spatial autocorrelation (-acf) function to generate
noise random fields.

Thanks,
-nick
