Dear all,

I would like to use the BIS Electrode Editor to create electrode location files of grid-electrode to use in EEGlab for further processing. I exported the .mgrid files as .txt files which resulted in a file with locationx, locationy and locationz for each electrode.

Which coordinate system is used for these location files and what is the origin of the coordinate system?
Can these location files easily be transformed to EEGlab ready formats like .ced or .loc? 

Thanks in advance.
