That will work; it may be clearer to use mris_fwhm, eg,
mris_fwhm --smooth-only --s sub-0006 --hemi lh --fwhm 5 --cortex --i
input --o output

Hi Experts,
This question may have been addressed elsewhereon the list, but I
can’t find a response.
I want to smooth BOLD data on the surface. First, I pre-processed the
data in FEAT with no smoothing applied. Then I registered the
filtered_func data to the anatomical using bbregister. I check the
registration matrix looks good by running this command (using
example_func as the reference):
* tkregisterfv --mov example_func.nii.gz --reg junk.dat --lta
reg/freesurfer/anat2exf.register.dat --surfs
I then resampled my data with mri_vol2surf using the following command:
* mri_vol2surf --src filtered_func_data.nii.gz --out
lh_func_native.mgh --srcreg reg/freesurfer/anat2exf.register.dat
--hemi lh --projfrac 0.5 --out_type mgh
I then want to smooth this data on the surface. I assume it would be
best to run mri_surf2surf and set the target and source subject as the
same? Such as this command:
* mri_surf2surf --srcsubject sub-0006 --srcsurfreg lh.sphere.reg
--trgsubject srcsubject--trgsurfreg sphere.reg --hemi lh --sval
lh_func_native.mgh--tval lh_func_native_smoothed.mgz --mapmethod
nnf --fwhm 5 --cortex
Please can someone on this list give me some advice on this? Are my
command suitible and/or am I missing anything?
Best wishes,
Mason
