Coverage, specificity, and reproducibility of unmodified 20mer arrays.

1True positive/false negative rates and false positive/true negative rates are expressed in brackets.2Since these Agilent arrays lacked barcodes for essential genes, estimates of false positives were not possible.3Correlation coefficients represent an average of all possible pair-wise comparisons within the indicated replicate type. Scatter plots are provided in the Supplementary material (Figures S4, S5, S6).4Comparison using average of all SUBarrays (n = 6) or Agilent arrays (n = 4).5These amplifications used highly similar biological replicates with the same dye-labeling scheme; however, by definition these are not technical replicates.6The lower correlation coefficient reflects the presence of numerous dye-swap artifacts.
