[BioC] help needed for GCRMA

[Memon, Farhat N]

Hi,

I am a new user of GCRMA package. I want to use GCRMA method to calculate expression values of some probeset for which I used the following code:

library(gcrma)
library(affy)
data=ReadAffy()
gcrma.set=gcrma(data)
gcrma.exp=exprs(gcrma.set)

According to my understand, this code will calculate the expression values of all the probesets. Now, I want to calculate the expression values of probesets excluding some of their probes.

If anyone can help

Regards
Farhat
