Automatic estimations of the sphere; each one
is based on a
different set of point (eg. scalp vertices, cortex vertices, EEG electrodes...). Select the best estimation, then adjust it manually if necessary. |

Graphically
edit the sphere: translation along each
axis, and resize. 1) Select one of these buttons 2) Right-click anywhere in the figure and hold the button 3) Move the mouse up or down |
