Hi Bruce,
I used Tksurfer to overlay fuctional onto anatomical. On the Load->Overlay window, I did indicate the functional *.bfloat and register.dat, but in the "Field" at the bottom, "Overlay layer 1 (empty)" is shown (inside "Field", all layers are empty).
I guess that something is wrong. (Should I do something for it?) (Even with that, I clicked the OK button. the Tksurfer image window flashes, but nothing is changed.).
Please help me. Nam.
