[BioC] Does 'arrayQualityMetrics' package work with Affymetrix Human Exon 1.0 ST Arrays?

Hi Núria,

The arrayQualityMetrics package relies on the affy and simpleaffy 
packages for much of the data processing. Unfortunately, neither of 
these packages is designed for a non 3'-biased array like the exon chip.

You want to use either oligo or xps for these data, or if you want to go 
off-campus, the aroma.affymetrix package will work as well.

Best,

Jim
