Hi Nela, try registering them with bbregister, then making sure the registration is correct with tkregister2.

Dear Freesurfer users,

I have tried to convert a volumetric SPM activity image from the form of a .nii file (created against the subjects T1.nii image) into a w file (paint file) to be overlaid on the inflated surface of the same subject's brain anatomy (created with Freesurfer recon-all), using the command below:

mri_vol2surf --mov ~/<name>.nii --out ~/<name>-rh.w --hemi rh --surf inflated --out_type paint --regheader $SUBJECT

However, the pattern on the surface does not *quite* match what I see from the volumetric image, and one of the reasons for this could be that I am not converting from volume image to surface overlay correctly - I would be very grateful, if there is a better way to do this, if someone could let me know.

Thanks and best wishes, Nela
