Hi All,

I am working with cDNA microarrays that were run only on one channel and I
have been trying to analyze them using the limma package. By changing the
read.maimages fucntion I was able to upload my data, but most functions
won't work with that RGList created due to the absence of a red component.

Is there a package that is more fit for such an analyses? Am I overlooking
an important function? Any ideas on how should I get past this?

Thanks very much and sorry for such a basic question.
Artur
