Hi, i am trying to use beadarray package for my illumina expression data.  Thing is whenever I tried readBeadSummaryData function with codes below, just to find empty QC information likie below.

My qcFile is controlprobeprofile.txt acquired from genomestudio. Is there anybody that has similar problem and solution? Thanks in advance!!

Data=readBeadSummaryData(dataFile, qcFile=qcFile, sampleSheet=NULL,
                           sep="\t", skip=0, ProbeID="Probe_ID",
                           columns = list(exprs = "AVG_Signal", se.exprs="BEAD_STDERR",
                                          nObservations = "Avg_NBEADS", Detection="Detection Pval"),
                           qc.sep="\t", qc.skip=0, controlID="TargetID",
                           qc.columns = list(exprs="AVG_Signal", se.exprs="BEAD_STDERR",
                                             nObservations="Avg_NBEADS", Detection="Detection Pval"),
                           illuminaAnnotation="Humanv3", dec=".", quote="", annoCols = c("TargetID", "PROBE_ID","SYMBOL"))
