Hi Thomas You can change the default inputted annotation columns by setting the "annotationColumn" parameter of lumiR function. These annotation information will be kept in the "featureData" of ExpressionSet (or LumiBatch) object. One thing I am not sure is what kind of IDs is used for your GenomeStudio output data. The Illumina Probe ID, like "ILMNxxx", is recommended. In quite a few cases, I found people using the Illumina address IDs as the probe ids, which will cause problems in ID mapping. If you would like to, you can send top 50 or 100 rows of your data file to me. But I will be out of town for a conference in the next few days, my reply may delay. Thanks for reporting the problem.
