Thanks Jim for the suggestions. I have been on leave for 2 weeks and will be
back at work on Jan 12th. (Just popped in to read a few emails!).
I will follow up on your point that affylmGUI should support the newer affy
chips. I'll discuss this with Gordon Smyth next week and let the list know what
we intend to do,
cheers,
