Table 5.
Detailed results of all PCA runs with respect to the second test, i.e. the identification of the 31 unknown mice. Mice in rows #1-20 are WT, whereas mice in rows #21-31 are R6/2

Only the ROC-supervised PCA (both with the covariance and the correlation matrix) diagnosed/identified correctly all of the 31 unknown mice. All of the WT mice (rows # 1-20) have positive PC1 scores, whereas all of the R6/2 mice (rows # 21-31) have negative PC1 scores.
