Dear Vladmir,
Thank you for your prompt reply.
As a SPM beginner I find these steps not immediate.
I am fine in using CheckReg button and select my subject's MRI. Then, I am
not sure how to compare this to the template. What can I "press"?
Sorry for this silly question,
Thanks,
Davide

Dear Davide,
I'm not sure it has to do with headshape, at least your F2 definitely is not
related to headshape. I suggest that you first check that your individual MRI
is approximately registered to the template (use CheckReg button and select
your MRI and the single subject template image in SPM/canonical). If not you
could use Display/image utility to reorient and translate your image. Then
use 'Coregister Est & Res'
button in SPM FMRI to coregister your individual image to the template and
reslice it and then use the output of that as the individual image.
Best,
Vladimir
