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

Hi FreeSurfer!

A colleague has retinotopic results that he would like to overlay on the FS surface (most likely fsaverage). The retinotopic data is in 2mm isotropic resolution. What would be the best way to be able to overlay this data correctly? Should he first warp the volume to the volume of fsaverage and then use vol2surf?

Any help is highly appreciated!

Best Heidi
