No, not in the current framework. Even if there were, fwhm=.66 would not
give you much smoothing. The intervertex distance is about 1mm, at
fwhm=.66mm, the nearest vertex would be about 3 standard deviations
away, meaning that the smoothing would be minimal.

So, is there anyway around this issue?

The smoothing works through iterative nearest neighbor smoothing, so the
fwhm is essentially discretized because you can't have fractions of an
iteration. It looks like fwhm=0.66 is closer to 0 iterations than 1
iteration, so it chooses 0.

Dear Surfers,
I am trying to use mris_fwhm to apply fwhm=0.66 to my fmri data (voxel
size 1 mm iso)using the below command:
mris_fwhm --s --hemi rh --smooth-only --i
fmcpr.sm0.self.projfrac_0.rh.nii.gz --fwhm 0.66 --o
fmcpr.sm0p66_surf.self.projfrac_0.rh.nii.gz --mask
Hi,
I'm getting an NAN value for some surfaces but not for others. Any
ideas? Both surfaces below were generated using an identical process.
