Old topic, but it is directly related, so I'll just continue it here. In the end I have the spots on the right place, but now it's not clear to me how to interpret the map. I have created three overlays (sign, log10 * sin, log10 * cos, like mentioned in selfreq.pdf) and loaded them all three in tk

Dear FS experts I would like to know whether cortical thickness and cortical surface area as computed by FS are independent of each other. My guess is that they are not independent, isn't it? Regards Jürgen Jürgen Häng
