Response patterns for cross-hybridizing probes. The x-axis is the index of a probe within a ProbeSet; the y-axis is the mean intensity of a probe across the samples in a class. A1 and A2 show only cross-hybridizing probes for the two classes in each experiment. For a different gene, B1 and B2 show a complete set of probes, with filled circles indicating the cross-hybridizing probes. Cross-hybridizing probes are much less consistent in direction and extent of change between disease classes and across sample sets than the filtered probes (see Figure 5 for comparison).
