Hi, I have just migrated our system froM MAS5.0 to GCOS (I wish I hadn't!) I am having problems reading the GCOS generated CEL files in - it seems that ReadAffy doesn't recognize the .CEL files. The error message is "The file does not appear to be a .CEL file". The .CEL files and the .CHP files (for the HGU133A) seem to be 5 MB each (in GCOS), in comparison to the same files in MAS5.0, which are 14 MB and 11 MB. Has anyone else migrated their system to GCOS and experienced the same problems?

The new GCOS uses a binary file format. Which the current ReadAffy() command does not yet parse (but should do so in the near future).
