[MINC-users] ray_trace colour maps and rendering labels

[EJ Nikelski]

Hi all,

   Two brief brief questions.  I have a volume of labeled structures
(AAL labels) that I want to render onto a cortical surface. Now,
ray_trace does the job, but the default continuous color maps don't do
a very good job of delineating adjacent structures. For example, as
the label numbers for the superior temp gyrus and MTG are quite close,
both get rendered in a subtly different shade of yellow (using the
spectral color map).   Questions:

(1) does anyone have a ray_trace formatted colormap, suitable for
rendering labels, that I can plug into the ray_trace "-usercc"
argument?

(2) does anyone know the required file format needed to use the
ray_trace "-usercc" argument, so that I can cobble my own together?

Thanks,

-Jim
