Figure 5.

Improvement in the correlation coefficients of array pairs for the same biopsy according to the minimum overlapping length (1 ~ 25 bp) and the percentage of used probes per probe set (10 ~ 100%). The correlation coefficients are the average of 14 arrays pairs. The probes are selected based on sequence overlap, and the probe sets with a sufficient number of such probes are used to recalculate the expression profiles. The correlation is enhanced with increasing number of minimum overlap length and, to a lesser extent, with increasing percentage of probes required for probe set.
