  1. The mean Log2 ratio obtained from analysis of five control slides by MAIA and GP for down- and up- notated populations of features with expected Log2 ratios of -1.58 and 1.58. The standard variation of the mean Log2 ratio is shown in brackets. The p-values from the paired t-test for the Log2 ratios are less than 1.4E-3. The p-values from paired t-test for the calibrated Log2 ratios are in range [1.7E0-7; 0.72]. For the full version of Table 2, including p-values from the paired t-test and estimated errors for the Log2 ratio, see Additional file 3.
