Hi Freesurfer Community,
I am trying to run a vertex-wise analyses of PET data.
I have already performed bbregister. Next, I did mri_vol2surf for each
subject, left and right hemispheres.
for i in `cat subjects`; do mri_vol2surf --src
FS6_${i}_MPRAGE_Neuro.nii/pet/pet2free_fsl.mgz --out
FS6_${i}_MPRAGE_Neuro.nii/surf/lh.PETSurface.mgh --hemi lh --regheader
FS6_${i}_MPRAGE_Neuro.nii --projfrac 0.5 --interp nearest; done
Is this command correct? Visual inspection on freeview looks OK.
How may I derive the group average from these individual surfaces and
perform the mri_glmfit?
Any help will be greatly appreciated.
Best Wishes,
Eli
