Hello 1)I need that to implement another normalization between arrays methods like GPA and vsn,LVS,CyclicLoess on the ddTGS(gTotalGeneSignal). 2)I am interest that to obtain an estimate of the gene signal using the RMA algorithm without the function rmaMicroRna ; First I read data into RGlist,then I get BG corrected and normalized between arrays in limma, but I don't know how can to obtain the median of the replicated probes. Please help me.
