Hi Karen,
I'm doing the exact same analysis as you, and have been searching the
list to try and understand how to do this next part of the analysis.
Have you come across the emails on the list dated 05/12/2006 entitled
"GLM GUI setup" from A. Silver? I think they explain most of the
points to do this step. I assue that they are still relevant for
the forthcoming release.
Also, if you've found anything useful to set this up...any extra info
would be appreciated.
