[Eeglablist] electrode location coordinates

Dear Maro,
here is a .loc file I made for easycap M11,
maybe you can adapt it to M10.
Best,
Johannes

Betreff: [Eeglablist] electrode location coordinates

Dear Users,

I have a problem registering electrode location in EEGLAB. I have a set of theta and phi angles (coordinates); however, they don't match with EEGLAB's one.

I attached  a text file contains theta and phi coordinates. (we have easycap's M10 cap).
Theta is the angle between the Z-Axis and the connecting line from the origin of the coordinates and the electrode position. In the left hemisphere Theta is less than zero, in the right hemisphere it is larger.
Phi is the angle between: 1. the projection of the connecting line from the origin of the coordinates and the electrode position onto the XY-plane and 2. the X-axis. Phi is greater zero in the front right and rear left quadrant and smaller zero in the front left and the rear right quadrant.

I just need to input electrode locations in EEGLAB and create location file. If anyone can help me to go through this step, it will be greatly helpful.

Best Wishes,
Maro
