We are trying to extract the header info in the affy CEL files, particularly the scan date and time and the scanner serial number. The affyxparser:readCelHeader and affyio:read.celfile.header function works fine for the text and binary CEL files. However when I tried them on the AGCC generated CEL files, the header slots are empty. Is there a way to obtain such info for the AGCC CEL files?

Thank you very much!
