Dear List, I am working on some Illumina-HT12 data. There seems to be a small problem in using the getChipInfo() method in lumi package. Thought the data is from Illumina HT-12 chip, the getchipInfo() returns "HumanWG6_V2_11223189_B" as chip version. Any information or suggestion regarding this issue will be really appreciated. regards, Mamun ################################################## Here is the LumiBatch object details.
