Hello,

This shell script may do close to what you want it to do, so you could modify it. It does it within AFNI using converted freesurfer surfaces.

If you see any errors please let me know.

not that I know of. When I have to do this, I save the data to a file, then call mri_surf2surf with a system call, then load the result back into matlab

Hi,

For a simulation purpose, I want to load a surface into Matlab, assign a random value (taken from a normal distribution) to each vertex, do spatial smoothing on the surface with a given FWHM (e.g. 5mm), then do some computations with the smoothed values.

I am wondering if there is a Matlab code that I can use for surface smoothing, similar to what FS-FAST preprocessing does in Freesurfer version 5 and above.

Thanks, Reza
