[BioC] Harshlight (or similar) for Agilent arrays

[David Garfield]

Hey folks,

I'm hoping that someone out there might be able to point my in the  
right direction for pre-existing packages/methods for applying  
corrections (like harshlight) to Agilent arrays.
I have an array in my dataset with some pretty clear spatial artifacts  
that I'd like to mask out. However, harshlight (the most commonly  
cited package for this sort of thing) appears to be only set to work  
with AffyBatch objects, not the RGLists that are generated by Limma  
(which seems the most natural way I've found for processing raw data  
from Agilent arrays).

Thoughts?

Many thanks,

David
