Dear everyone,
when running F-contrasts in SPM or second-level analyses with GLMflex, no extent threshold is given. 3dClustSim or AlphaSim seem to be an option, but I'm unsure how to use them.
Is there a walktrough guide how to define extent thresholds with these (or any other) scripts? Do they work with Windows (I might be wrong but it seems AFNI requires Unix or Mac, which I don't have)? If no or if a VM is required, are there any other well-documented solutions to get cluster-level p-values or at least an extent threshold of k = x voxels?
Thanks,
Helmut
