Dear All, I am analyzing Illumina array data using the "lumi" package (great package, thank you for developing and maintaining it!), but seem to have some trouble reading the control data in the LumiBatch object. > controlData = "2011-144 control probe profile.txt" > Cell.lumi = addControlData2lumi(controlData, Cell.lumi) Inputting the data ... Annotation columns are not available in the data. I tried adding the the controlData as a lumibatch object, but that did not work either. The first column of the controldata file is Target_ID, the second probe_ID and the rest is gene expression output. Any suggestions? Thank you! S.A.
