All,
 
I am new to xps and am having trouble reading in the cel files.
 
I got the 3 correct files from affymetrix and created a scheme removing the first 12 lines from the annotation  file (fix 1)
 
 
I then read in my scheme:
hgu133plus2<-root.scheme(paste(.path.package("xps"),"schemes/hgu133plus2.root",
   sep="/"))
 
and then try to read in the CEL files.
celdir2<-"C:/McMasters/test"
data.test3<-import.data(hgu133plus2,"tmp2",celdir=celdir2, verbose=FALSE)
It worked 1 time and now causes R to crash.  I am trying to read in 40 CEL files 50,000+ genes on a 4G machine.
 
Does anyone have any suggestions of another method to read a large amount of CEL files.  If I try using Read Affy()  to read in, I don't have the space to allocate.  
 
Thanks for the  Help,
