Hi,

I would like to know how many controls can I compare to my samples in GEO2R? What I mean is, if I choose 10 samples should I compare them with just 10 controls or It is possible to add more controls , if the  microarray study provided. For example: 10 samples/ 20 controls 

and how about visa versa? 

Another thing is, for gaining significancy (adjusted p-Value) , is it possible to select controls or samples that are more similar in expression , or I should select them randomly? Could it be a kind of normalization? 

Thank you very much
