Goal and characteristics of statistical tests used to evaluate electrode configuration simulations

Goal	Distribution of data	Type of test	Power of test
^aTest differences in fiducial movement between brain segments after rigid registration only	Highly skewed right	Kruskal–Wallis	χ² = 3.00e+05
^bTest differences in fiducial movement between brain segments after rigid registration followed by nonrigid registration	Highly skewed right	Kruskal–Wallis	χ² = 2.33e+05
^cTest differences in fiducial movement after rigid registration and rigid registration followed by nonrigid registration	Highly skewed right	Mann–Whitney U	Z value = 30.4165 Rank sum = 1.01e+12
