Hi Susan,

The readQC function is still present in version 2.2.0, but it is
called from within readBeadSummaryData rather than being called
directly by the user.

The fact that you have no QC information in your ExpressionSetIllumina
data object could be to do with the format of your QC data. You should
check that the qc.sep, qc.skip and qc.columns arguments are correct.
Do you get any warning or error messages when running
