[BioC] Papers mentioning duplicate spots

[Gordon Smyth]

I am looking for references to published papers on microarrays which 
mention duplicate spots, i.e., replicate spots on the same array containing 
the same probe. The treatment of the duplicate spots can be very brief, 
e.g., just to say that log-ratios from duplicate spots were averaged before 
further analysis. I am particularly after papers in mainline biological 
journals. Any references would be much appreciated.

Thanks a lot
Gordon
