He should recon-all the anatomical data for the subject, register the fMRI to the anatomical (bbregister), then use mri_vol2surf to map the fMRI to the subject's anatomy. Then use mri_surf2surf to go to fsaverage if needed (though why?). Also, the retinotopy results will look much nicer if the fMRI data are sampled onto the surface and smoothed and analyzed there. doug
