Dear Members (and especially Marc Carlson),

I have few questions:

1. I was wondering whether HsAgilentDesign026652.db is the latest updated
database for Agilent 8x60K human gene expression arrays or is there any
other file?  I have been told by Axel that HsAgilentDesign026652.db cover
the oligos used by the Agilent 4x44Kv2 arrays, so I am not sure if I can
use this for 8x60K arrays.

2. If I can indeed use HsAgilentDesign026652.db for 8x60K arrays, is it
possible to use it as annotation file for Agi4x44PreProcess package so that
I can use the same codes from this package to analyze 8x60K arrays?

3. If I want to create an annotation file to be used in any of the
packages, what are the requirements (files, tools etc) for it? I have an
annotation file in excel format given to me by my microarray service
provider, so If I want to use that annotation file in Agi4x44Preprocess
package (or any other package that requires this file) what should I do?

Thanks a lot in advance for all your suggestions!

Cheers,

Karthik
