[BioC] Preprocessing affymetrix data

[Ingunn Berget]

Hi
This is more of a theory/litterature question than use of BioC.

I know there are many different methods for quality control and 
preprocessing of affymetrix data, some use the mismatch probes, others 
don't. Does anybody know about reviews or comparative studies that compare 
the different methods and how they perform on data. A quick view of the 
bioconductor packages indicate that there are at least 5 packages that can 
be used for preprocessing of affymetrix data, how much do they differ?


Best regards
