Hi All, In Illumina microarray, there are a few probes for one gene and each probe may represent the corresponding RNA isoform or a few probes may represent only one RNA species. Now I want to integrate several values (or intensities) from those probes for one gene into one value to do further analysis. I do not think simply averaging values is good idea. Is there anyone who has experience in this field? Please give your advice. Thanks, Hai-Ri [[alternative HTML version deleted]]
