Hi Ruopeng,
Thanks for the answer. Actually, the results I describe are already with
changes to the color scale. It is still quite coarse though in my opinion.
Actually have an added wish now: I want to be able to plot circular data in
freeview (retinotopic mapping), is this possible?
kind regards,
Frank

If you load the data as overlay in freeview, you should be able to
adjust the color scale to see the gradient.
