Hello, I've specifically adopted Freesurfer for its ability to map a brain into a sphere. I've ran a subject's structural data through the recon-all pipeline using the -all option. With this reconstruction completed, I'd like to overlay functional data on the sphere. More specifically, I'd

Hi Luis if your functional data is mapped onto the surface (i.e. with mri_vol2surf) then it is already on the sphere. All the surfaces for a given subject's hemisphere are topologically equivalent, so you can simply look up the same vertex index on the ?h.sphere (for the metrically optimal
