...@nmr.mgh.harvard.edu: Does the BPM toolbox (what's that?) not give you cluster correction? You can try using mri_volcluster with the --grf option, but you'll need to know the FWHM. Afterwards you can map the result to the surface On 4/13/15 10:46 AM, Matthieu Vanhoutte wrote: Hello Douglas, Thanks
