I really thank you for the answer
If possible I would have another question.
By running the RetinoProcDemo script, in the eccentricity map obtained through @Proc.All I have that the apex of the occipital lobe is activated for higher degrees of eccentricity and then the trend goes decreasing going toward the center of the brain (pic1). In one article, however, I saw that the output of SUMA is the opposite (pic2). And this happens in many other papers. Why this difference?
