You can take fmcpr.up.sm4.fsaverage.lh.nii.gz and export it back to the native functional space with mri_surf2vol, something like mri_surf2vol --surfval fmcpr.up.sm4.fsaverage.lh.nii.gz --hemi lh --fillribbon --reg register.dof6.dat --template template.nii.gz --o fmri.surf.nii.gz and mri_surf2vol --surfval fmcpr.up.sm4.fsaverage.rh.nii.gz --hemi rh --fillribbon --reg register.dof6.dat --template template.nii.gz --merge fmri.surf.nii.gz --o fmri.surf.nii.gz The output will have both hemispheres doug

Hi, I have run preproc-sess to analyze fMRI images. I'd like to analyze fMRI images in the individual space, but I found that the final output (i.e., fmcpr.up.sm4.fsaverage.lh.nii.gz) were already spatial normalized. So, How to just smooth fMRI images in surface space and export them as the co-registered fMRI images in volume space? I think it could start at "fmcpr.up.nii.gz"? Thank you in advance!

Best, Xiangyu Long
