+and sample-independent controls present on the array and user adjustable
+thresholds.  In depth exploration of bad quality samples can be performed using
+several interactive diagnostic plots of the quality control probes present on
+the array.  Furthermore, the impact of any batch effect provided by the user can
+be explored.")
