Table 2 Precision ratio summary for GeneChip and CodeLink microarray platforms. Precision measurements were calculated from signals above noise across the arrays being compared. For CodeLink, there were 7,882 and 6,603 ratios, on average, for each pair-wise array-to-array comparison, within brain and pancreas respectively. For GeneChip, there were 6,734 and 5,137 ratios, on average, for each pair-wise array-to-array comparison, within brain and pancreas respectively. For each of the 10 pair-wise combinations, the ratio range within 95% of the ratios fall was calculated. This table contains the average and standard deviation, in which 95% of ratios fall within, across all 10 pair-wise array combinations within a sample.
