[BioC] a thin hibridisation line

[kfbargad at ehu.es]

Dear list,

has anyone noticed that there is a thin horizontal line across the 
whole array with different intensity about two thirds down the array, 
visible when looking at the pseudoimages generated using residuals in 
affyPLM? I have seen this line in quite a few of our arrays, even 
different species (rat, human), but maybe only in the new 2.0 
versions. Has it got anything to do with the new version design?

Regards,

David
