Hi all,

I am very new to microarray analysis and I'm running into a few issues with
normalizations for the print order. The arrays I am working with are
"home-made" and the spots are duplicated and separated by columns.

My problem arises from the fact that there are non-informative spots (i.e.
landing lights and empty spots) that are not duplicated. Would it be
acceptable for me to take all these uninformative spots and shift them to
the end of my spots list so that they didn't interfere with the informative
and properly duplicated spots? Could this interfere with the results that
I'd get from the function normalizeForPrintorder?
If shifting the position of my spots like that isn't a good idea, does
anyone have a suggestion to me?

Thank you all very much,

Artur Veloso
