I am struggling to get data from Agilent cDNA arrays into BioConductor. It seems to me much easier to get the data in affy's normalize.loess() than in the other cDNA array packages. Given that "one who get a bargain get what he pays for", does anyone has comments, recommendations or warnings to share about using an Affy normalization procedure on cDNA data? Thanks, Joel M.

Why not just use Limma and the corresponding tools? It's FAR easier that way. That way you actually get what you pay for, rather than far less...

Thank you for pointing this out. I had not seen that read.maimages() can process 'agilent' files and thought all the data structures had to be filled in manually.
