     This data set is a small excerp from an Affymetrix hgu133plus2
     micro array experiment. It contains 8 chips from 4 patients, 2
     B-cell-ALL (acute lymphoblastic leukemia) and 2 T-cell-ALL
     patients. Two samples per patient were hybridized onto the chips,
     one before treatment and one after 6 hours GC (glucocorticoid)
     treatment. From every chip only 100 probe sets are included in
     this small dataset.

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

     An 'exprSet' containing the expression values from 100 genes on 8
     different chips.
