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. > Is there any way to combine duplicated spots by ID or name in Limma?
