_D_e_s_c_r_i_p_t_i_o_n:

     Contains expression values for 250 probe ids with 8 samples. Two
     covariates are provided. Expression comes from the 'hgu95av2'
     chip.

_D_e_t_a_i_l_s:

     The data is real but anonymized. 250 genes expression values were
     chosen at random from an existing exprSet. Another 250 probe ids
     were selected at random and were assigned to the expression
     values. That way, expression values do not correspond to the true
     probe ids.

     Post-processing was done with 'rma()' in 'affy' 1.2.23.
