Figure 3From: An algorithm for automatic evaluation of the spot quality in two-color DNA microarray experimentsExamples of spots with different types of distortions. A) Large deviation from the circular shape (GS = 1.6); B) Bright piece of contamination within a larger circular spot, resulting in a low value of the IS parameter (IS = 1.71); C) Merged spots (UB = 2.98).Back to article page
