[BioC] help with lumiB

[Pan Du]

Hi Leon,

I guess the problem was caused by the mismatch between the column names of
control probe data and expression data. Can you send me the return of
sessionInfo() and the code of adding control data to the LumiBatch object?
It will be helpful for me to find the problem. Thanks!


Pan
