[BioC] expression levels of individual probes

[Chris Dawson]

Hi there,
I have a number of short RNAs that have high homologies to a number  
of  individual probes in the Medicago Affymetrix Genechip (http:// 
www.affymetrix.com/products/arrays/specific/medicago.affx).  I'd like  
to be able to see for a few hundred probes which individuals, for  
example Medicago:AFFX-CreX-5_at:587:698, have high fluorescence  
levels and which do not. I realise binding efficiencies differ for  
individual probes, but I am only looking for indicative data. Sorry  
if I am not clear with proper terminology, I've only worked with pre- 
made gcrma processed data sets before, not individual probes.
Cheers,
Chris
