XYZ Coordinates for 16 channel Electrodes on OpenBCI Cyton + Daisy

Hi,

1. Can you help me on 16 channels locations (x,y,z) coordinates for OpenBCI electrodes?

2. It would also be of great help, if you can provide montage to be used in mne, that replicated exact electrode locations in openbci headplot.

Note: The x,y locations are already provided, and I am aware about it, but I would be needing z axis too.

Cause:

I am using it to use as a montage in mne, since the electrodes placements for standard1020 system varies from the one used in OpenBCI. Plotting 16 channels from standard 1020 systems gives a diffferent visual than what openbci headplot shows.

Below figure you see is a plot for 16 channel electrodes (with openbci provided channel names), from mne using standard_1020 montage:

Below is a 16 channel electrode placement for openbci:

Hope so you can spot the difference between two.
Thanks,
Pluto
