Verify Electrode Coordinates

The electrode locations can be inspected in a 3D view using the menu command File -> Head surface points and sensors -> View. The fiducials (pre-auricular points and nasion) are plotted as purple cubes, the electrodes are plotted as red disks. By clicking on a disk, the electrode label of a particular location, and its coordinates, can be checked. The calculated head radius is also given (default value is 85 mm if no electrodes were digitized).
