Hi SPMers,
I am reading the paper of Friston 95 and Ashburner 97, and I don't
understand why in the spatial normalization step, an additional parameter is
added to estimate intensity mapping between the images. Could you please
explain to me this process?
Another point please, in fact I am using SPM5 and in the manual I didn't
find which optimization problem have been used in the affine transformation.
Is it The Gauss Newton one?
Thanks for your help experts,
Best regards.
