Hi there,

Another tip would be to use the barcode present on each Agilent array (or if you used an Agilent Scanner, it's the part of the filename between the first and second underscore, if I recall correctly). Visiting the Agilent website (chem.agilent.com) and downloading the annotation/gene file results in a window where it asks for this barcode. After submission the correct annotation files will be displayed for you to download! 

For more details, I recommend visiting the Agilent website.

Best of luck,

They are different platforms. You need to use the one that matches the array you 
are using.
