Thanks! Wei,

I have found and solved the problem. Please check the latest version: lumi
1.5.18
Because the QC slot keeps the information of samples not the genes,
subsetting the genes will not change the QC slot. Only subsetting the
samples will also subset the ³sampleSummay² and ³BeadStudioSummary² in the
QC slot. 

Have a nice weekend,

Pan
