[Gmod-help] storing average expression data in MAGE module of Chado?

[Dave Clements, GMOD Help Desk]

Hi Ian,

I am afraid that you may possibly now know more about the MAGE module
than anyone at the GMOD Help Desk.  I don't believe that any of us
have ever worked with it.

I'm forwarding your query to Brian O'Connor and Allen Day, whom I
believe are the two people who contributed the MAGE module to GMOD.
Brian, Allen, any ideas on Ian's question?

Regards,

Dave C.
