Hi

I have two sets of data generated from Affymetrix mogene 1.0 ST and the Affmetrix mogene 1.1 ST Array. I am trying to normalise them together with the following but it did not work. How do you read two types of CEL files with identical gene lists but different chip dimensions?

>library(oligo)
>library(pd.mogene.1.0.st.v1)
>library(pd.mogene.1.1.st.v1)
>celFiles <- list.celfiles()
>Rawdata <- read.celfiles(celFiles)

All the CEL files must be of the same type.
Error: checkChipTypes(filenames, verbose, "affymetrix", TRUE) is not TRUE


Cheers
