\begin{Description}\relax
Simpleaffy requires a definition file describing the qc probes,
spikes, alpha values, etc. for the array of interest. This is used to
initialize the QC environment for the array (usually implicitly within
the \code{\LinkA{qc}{qc}} function), by a call to  
\code{\LinkA{setQCEnvironment}{setQCEnvironment}}. This function can be used
to check if the qc environment has been set up for the current session
