Creating Colour Maps [message #35223]

Hi,
I'm relatively new to IDL and trying to create brain maps using
diffusion tensor magnetic resonance imaging and display these images
effectively in IDL. I have a map of my image and I want to specify the
colours of the pixels not only based on the intensity value of the
pixel, but also on the direction of the principle eigenvector
associated with each pixel, thus the colour will be associated with
direction and the intensity with magnitude. I have no idea how to do
this, I know how to create a colour map based on the intensity value
but I don't know how to take into account another factor that is not
associated with the image but with another dataset and use this to
determine the RGB mix. If someone could help me that would be
fantastic!

Thanks so much

Kate Morgan
