ROC curves for different hybridization temperatures. The information content of the measurements is reflected by ROC curves for the prediction of sample type (male vs female). Prediction performance was obtained independently for each gene by 6-fold cross-testing (Fig. 3). The ROC curves show averages over all genes. Comparing performances at different hybridization temperatures, the largest areas under the curve were observed for 51°C and 50°C (b). More subtle differences of the ROC curves can be examined in the zoomed detail plot (right panel), which identifies 51°C as optimal hybridization temperature.
