Hii everyone,

I have 20 samples with Illumina Mouse-Ref 8 V2 microarray chips, and output from GenomeStudio as two files for each samples:

• named with sample_beadTypeFile.txt (header as Illumicode + N + Mean.GRN + Dev.GRN)
• named with sample_perBeadFile.txt (header as Code + Grn)

I aim to summarize the data into a format with headers: Illumicode, mean.Grn (for each sample), and detection p-value. However, my attempts using the beadarray and lumi R packages have not been successful.

I already read all _beadTypeFile.txt in list with read.table or BeadSetIllumina(storageMode: list)with readbeadMSV, but not sure how to integrate all samples with Probe_Id, sample_ID, Detection Pval. Thanks a lot for your suggestions and ideas!

Best regards, Na
