Hi Andrew,
There is nothing special with these RGB-color coded images, it is just the way they are displayed. FSLview reads the vector components in each voxel and displays them as an RGB color. So, it is up to whether a software package offers this type of display, not on some special information stored in the image.
Cheers
Stam

I am interested in drawing ROIs using Analyze, but using the color map as a supplementary image.
