Hi there I've been trying to annotate my Illumina Mouse Ref8 gene expression array data imported in BRB Array Tools. I downloaded the lumiMouseAll.db and the lumiMouseIDMapping packages from Bioconductor in R. But I still get the error "lumiMouseAllMAP" not found. Is this a different package? Any suggestions on how to get it to work? I don't know if this is relevant but if I try to annotate the data through SOURCE or bu matching the dataset against genelists I get the error "Error in Get Gene IDs From File: the Gene ID Type string did not match any of the header labels in the Gene IDs binary file project". Does that mean there is something wrong with the primary data file? Will that affect the lumi annotation too? Thanks! Tejas [[alternative HTML version deleted]]
