hello Steffi, In 'lumi' one needs to import the data out of BeadStudio in a particular order of various columns (it can be arranged outside BS also). The columns in order are- 1) TargetID 2) ProbeID (this is different from the Probe_ID col) 3) Avg_Signal 4) BEAD_STDER 5) Detection Pval These are the cols. that are mandatory. Apart from them, annotation cols. can also be added. Info. about them is given in the "Using lumi.." pdf that comes as vignette with the package. Also while importing the data using *lumiR* command, one needs to specify the *grep* pattern of the column headers by which *lumiR* would recognize which col. contains what. Though the deafult output has the columns in order for *lumiR* to work in default settings, but just in case. I haven't analyzed HT-12 but WG-6. And above method works fine. *lumi*takes " *ProbeID*" as the unique identifier (v 3.0 chips onward) and I didn't encounter a 'duplicate ID..' message. I'm also unsure of the 'Inf' message. Maybe try importing the data with specifications for most of the options, i.e. col. grep pattern. regards amit mandal Graduate student Genomics & Molecular Medicine lab IGIB, Delhi On Tue, Sep 8, 2009 at 7:30 PM, stefanie.figura <figura@uni- muenster.de="">wrote: > Dear all! > > > > I tried to analyse the Illumina HumanHT12 chip with the lumi package and I > have some questions about the import and the results of the quality > control. > > > > My first question is which columns have to be exported from BeadStudio at > least?
