If you have an mri volume with fidicials where the eletrodes are, then you can load the volume in tkmedit and find the points. Then View->Information->VolumeRASCoordinate will display the "Volume RAS" in the control panel. Thse are the same coords as the surface.

Hello

I need to import a file with the coordinates of the EEG electrodes (*.elc) obtained in the system POLHEMUS FASTRAK into the FreeSurfer system. Could I do that with the current version?

Thanks in advance
