Dear Doug, unfortunately, I don't know how to define the source (EPI) and target (smoothwm) within the mri_surf2surf command to apply smoothing on the FEAT functional data.
My aim is to apply smoothing of the FEAT functional data AFTER being resampled to the smoothwm (to avoid deficient smoothing due to attached cortical banks given by VBR-approaches) mri_surf2surf --s PM_02173 --hemi lh --sval ??? --fwhm 10 --trgsurfval smoothwm is smooth-out a better option? --smooth-out (to apply smoothing after resampling to the smoothwm) ps: Might tksurfer be an alternative? Using: tksurfer subject lh smoothwm -overlay [FEAT functional] -overlay-reg [...anat2exf.register.dat ] and apply smoothing by using Tools--> Surface --> Overlay Smoothing?

I want to apply smoothing on the functional data preferentially on a surface which doesn't suffer from metric distortions (like the inflated OR sphere). I thought about using the smoothwm surface. Questions: Which command can I use for smoothing the feat functional data on the smoothwm AND furthermore, how can I extract the cluster maxima afterwards??? I'm thankful for any helpful comment, Greetz, Christopher _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu<mailto:Freesurfer@nmr.mgh.harvard.edu> https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
