The key is to create a registration matrix between your pet volume and the freesurfer orig.mgz volume. You can do this with spm (just register the two together), then run something like:
tkregister2 --s yoursubjectname --mov pet.img --regheader --reg register.dat
this will bring up the interface that you can use to visually inspect and/or modify the registration.
You can then run something like:
tkmedit yoursubjectname orig.mgz -overlay pet.img -overlay-reg register.dat
and
tksurfer yoursubjectname lh inflated -overlay pet.img -overlay-reg register.dat

Hello all
How can I use corregistered PET functional data instead of fmri to overlay freesurfer's anatomical volumes and surfaces?
Some tips are welcome
Thank you in advance
Jorge
