Hi Dave If you click the icon with the white "i" surrounded by the blue circle at the bottom of the screen next to the visibility and lock buttons it will open up a window in which you can control the colour of the overlay. So if you want to have the negative as blue- select the lookup table blue-lightblue.

I know that some statistical packages can show you increased activation for a given contrast (in red) and decreased activation (in blue). Is this possible in FSLView?
