3dClustSim Compatibility with SPM files

Hello All,

I am hoping to use AFNI’s 3dClustSim to determine the number of voxels in a cluster necessary to maintain significance at various p-values. I have preprocessed all of my fMRI data using SPM. Is it possible to conduct this analysis on data that has been processed using SPM? If so, how would I go about doing this.

Thank you,
Molly Memel

There are a couple of other (and probably better) options in terms of FWE correction in addition to 3dClustSim. Here is a starting point that also includes some guidelines for 3dClustSim:
