I was able to view the statistical maps (from FSL) on the subject's surface following the tutorial (FsTutotial/FSLFeatFreeSurfer). I would like to see the same image in Matlab. I could show the subject's surface as well as the the cortical parcellation in Matlab by modifying the functions freesurfer_read_surf.m and read_annotation.m. I do not know how to overlap the statistical map onto the surface then. Is there any Matlab function I can use? Thanks.
