Hi James
if it is registered to MNI space I guess you could do vol2surf directly on fsaverage, but it won't be very accurate and will for sure miss things

Thank you Bruce. What if the nifti volume has not been processed at all in Freesurfer? My only aim is to illustrate an overlay on FSAVERAGE, with the obvious caveat of skipping surface construction for this nifti. Thanks, James

1. Use bbregister to register the fmri to the recon surfaces 2. Use mri_volsurf to sample the fmri data onto the surface 3. Use mri_surf2surf to map from the individual to fsaverage cheers Bruce On Tue, 9 May 2017, james pardon wrote: Dear All, Apologies in advance for the naive question. Could you please let me know what is the best way of transferring a nifti overlay volume to fsaverage, solely for illustration purposes? I think I should start by registering with fsaverage volume and then overlay with Freeview, but I'm not sure what tools from Freesurfer I should use for 1) between subject volume registration (nifti volume to fsaverage volume) 2) fsaverage volume to fsaverage surface. Thank you, James
