[BioC] Affy U133 array CEL files - how can i see individual probe signals?

[Deb [guest]]

Hi

Normally,in order to view probe signals from an Affy U133 array i import the CEL using 

x<-ReadAffy(*.CEL)

Then have to 

y<-rma(x)

Which only allows me to see the mean signal for all probes of the same ID, even though they represent different sequences associating with the same target gene.

I want to be able to see the signal for every individual probe on the array.

Does anyone know of a way of doing this?

I have also converted the .CEL file to .txt using Affymetrix Power Tools but it doesn't give me Probe ID names, just x/y co-ords of the probes.

Cheers.
Deb
