Hi,

Thank Cary Vincent and Christian for answering my previous question. I'm able to import Mouse Exon 1.0 ST array now.
Due to my RAM memory restriction, I can only import one CEL file each time. Here is my code and it works.

R>biocLite("pd.moex.1.0.st.v1")
R>biocLite("olig")
R>exonCELs <- list.celfiles(full.names = TRUE)

R>affyExonFS1 <- read.celfiles(exonCELs[1:6])  #First read 6 CEL files, then save the results and clear the memory
R>affyExonFS2 <- read.celfiles(exonCELs[6:12]) # Read another 6 CEL files, and load the first 6 CEL files

Now my question is how to merge affyExonFS1 and affyExonFS2. My following code did not work
R>library(affy)
R> merge.AffyBatch(affyExonFS1,affyExonFS2)

Error in function (classes, fdef, mtable)  :
unable to find an inherited method for function "intensity", for signature "ExonFeatureSet"

Can anyone help me to merge CEL batches, affyExonFS1 and affyExonFS2, imported by oligo package read.celfiles() function? Note CEL is imported by oligo package instead of affy package. I could not find a merge batch function in the oligo package.

Thanks!

Daisy
