Hi Katie, the color wheel became difficult to support (and I think it is 
inferior for viewing for various reasons). There is an alternative 
called rtview. It is not in the distribution, but you can get it from

ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/rtview

Look at the --help to see how to run it.
