Hi, I have output file of Illumina microarray. "Array Content = HUMANREF-8_V2_11223162_B". Data contains the Probe ID and target id. But I am unable to read the file with probe ID. The error it shows. “Annotation columns are not available in the data. Duplicated IDs found and were merged! Error in se.exprs[selInd.i, ]^2 * (beadNum[selInd.i, ] - 1) : non-conformable arrays In addition: Warning message: In lumiR("probe1.txt", lib.mapping = "lumiHumanIDMapping") : The raw data should not be normalized in BeadStudio. “ Any suggestion for this problem??
