Dear expert,
After importing the .raw file from 128-Ag/AgCl electrodes mounted elastic cap (Geodesic Sensor Net, Electrical Geodesics Inc., Oregon Eugene, USA) , the pipelines are: add EEG positions-ICBM152-EGI-GSN Hydrocel 128 E1. No error or warning occurred, but the sensor topography looked strange, see the following picture
Is there anything wrong?
I think it looks like what it is intended to: a projection in 2D of the 3D sensor positions.
If you don't like this, try using the option "2D Disc".
And first of all, make sure the 3D positions of the EEG electrodes are correct by displaying them on the head surface.
Yes, the 3D positions on the head surface works well
Thanks for your reply, Francois!
Best regards
Zhang
