[BioC] AffyRNAdeg slopes

I believe the consensus on this is that it is more important to have
samples with comparable slopes than it is to actually quantitatively
assess the slope itself. I have worked with clinical samples that gave
me rather steep curves but the data was very good. Its just good to see
that you don't have any samples with curves that are way out of what the
others are doing.

Yours, Lawrence

Subject: [BioC] AffyRNAdeg slopes

Hello everyone,
I was wondering what are acceptable values for the slopes generated 
using summaryAffyRNAdeg in the affy package.  I assume 0.0 would be the 
ideal, but what values would be considered 'of concern', or too high?  
Any thoughts from users of the RNA deg function?
