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 |
