Hi,

I have been using R (R x64 2.11.1)  for generating images from CEL files, using the standard affymetrix gene array. I was wondering if this is possible using the exon array? I tried to do it with the standard packages, but it did not work. Here are the steps that I would normally do using gene array:

1.Change directory
2.Load Affy and AffyPLM package
3. object<-ReadAffy()
4. newobject<-fitPLM(object)
5.image(newobject,which=1,"resids")

Is it possible to generate images for exon arrays and if so how do I do it?

Thank you
