Box and whisker plot for the null distribution produced by the permutation test for the final SVMacc solution (linear SVM, average of all available epochs, all sites, temporal window 0–900 ms). The center of the box is the median of the distribution. Box limits are the 25th and 75th percentiles, while the whiskers extend to the 2nd and 98th percentiles to delimit a two-tailed 4 % threshold for significance. Accuracies that are observed in the null distribution, which exceed these limits are indicated by red cross marks. The observed accuracy of the true SVM solution (mean error = 5.5 %) is indicated by a blue ellipse. (Color figure online)
