Quality Metrics for Each Array

Global metrics are those quality measures that are reported as a single value per array (Figure 3.19). These global metrics are detailed in the GeneChip® Expression Analysis Technical Manual at http://www.affymetrix.com/support/technical/manual/ expression_manual.affx and in the GeneChip Expression Analysis Data Analysis Fundamentals at https://www.affymetrix.com/support/downloads/manuals/data_ analysis_ fundamentals_manual.pdf. Table 3.4 serves as a reminder of quality measures we find useful.

Collectively, these metrics monitor system performance and sample quality.
