Dear all, I am having problems using the "lumi" package to read in my data set for miRNAs (Illumina platform). What I just got is a data set (raw values) SYMBOL sample1.AVG_Signal sample1.Detection Pval sample1.BEAD_STDERR sample1.Avg_NBEADS ...more columns at end ======= ================= =================== ==================== ================== ILMN_3167304 -10.5716 .8341108 5.761263 255 .... lumiR fails on this data...I don't have any annotation files at this time...this is the v2 illumina miRNA array with 1146 miRNAs. Any help in reading into lumi would be greatly appreciated!! > X=lumiR("FinalReport.csv",inputAnnotation=FALSE,convertNuID=FALSE) Duplicated IDs found and were merged! Error in function (classes, fdef, mtable) : unable to find an inherited method for function "annotation<-", for signature "LumiBatch", "NULL" In addition: Warning messages: 1: In as.vector(data) : NAs introduced by coercion Nusrat Rabbee Bioinformatics [[alternative HTML version deleted]]
