The duplicated spot method in limmaGUI is not applicable if not all
probes are duplicated. The
recommended procedure is that you simply treat the duplicates as
independent probes.

I don't know what you mean by this.

No. Well, I can imagine some special arrays with a small number of
non-duplicate control spots,
for which the non-duplicated could be removed. But this would only be
sensible for special
arrays, and it involves some checking that you're not likely to do if
you're using limmaGUI rather
than the command-line package.

No.
Best wishes
