I've made an RGB data set with color coding from DTI data - if you care it's principle eigenvector * fractional anisotropy. It overlays very nicely in the 2d viewer on top of a hires T1 weighted scan.
I'd like to render it like any other fim. What should I do? Should I try and go down the path of making a color table with a huge number of entries and turn the brik from RGB to index? or is there a more straightforward solution I'm missing?
Thanks,
Souheil
