Dear member,

I am unable to read an Affymetrix Command Console (new Affymetrix Software) generated .cel file by affy function ReadAffy().
I am getting the following error:
Error in read.affybatch(filenames = l$filenames, phenoData = l$phenoData,  : 
        Is M:/Sohail/AGCC_files/JSMK_S428C.CEL really a CEL file? tried reading as text, gzipped text and binary
Do these files have to be converted to GCOS format?
Or is there an upgrade for the affy package.
