Dear Freesurfers,

Is there a way to smooth already preprocessed functional images* (FEAT, FSL), which I coregistered to the reconstructed surfaces (reg feat2anat), on the cortical surface?

Furthermore, I would be interested in finding the cluster peak vertex after smoothing the EPI on the reconstructed surface. I know that Hagler et al 2006 talked about a "vertex search method" to find the maximally activated vertex on the surface.

Kindly regards,

Christopher

*the FEAT preprocessed and 1st level statistics FEATs are not smoothed to avoid blurring across attached gyri
