     nsFilter is the nonspecific filtering boolean values for the
     sCLLex ExpressionSet object.  One filter was use: genes with an
     IQR greater than or equal to the median IQR (IQR performed on the
     rows of the expression matrix) have a TRUE value (passed the
     filter) and those that had an IQR less than the median have a
     FALSE value (did not pass the filter).  We only filtered on
     variation.

_F_o_r_m_a_t:

     A named vector of logicals.  The names are the Affymetrix
     identifiers and the values are booleans.
