Restoration effects. Comparing the log fold changes in the MAS5 algorithm before and after restoration. Vertical axis, log fold change between the original expression values and the restored values (Orig vs median). Horizontal axis, log fold change between the original and blemished chips (Orig vs pox). Notice three straight lines through the plot. A diagonal line represents changed expression values that were not restored by Harshlight. A vertical line shows a few cases in which Harshlight incorrectly affected the expression values. Most points lie near the horizontal axis, showing that Harshlight restored values closer to the original.
