Hi.

Does anyone has the location file for the 64 bit EEG electrodes?
Basically, I need to know the exact coordinates that biosemi use for the headcap. XY coordinate or polar coordinates.

Thanks.

Thanks. I read it but dont quite get it. How do I translate it into 3D coordinates? For example, FP1 is -92 and -72. What would it be in 3D coordinate? Any pointer?
