Hello all, 

I've recently started using Surf Ice to do my surface renderings and I really love it! It's great! 

I just had a question regarding the overlay function which give me some problems so far. Specifically when I add an overlay .nii image, Surf Ice does not allow me to change both the threshold (MIN and MAX) and the color. I mean that if I change those parameters the overaly suddenly disappear. Any tips about it? 

Thanks in advance
