So the error is probably somewhere between the export function and the plotting in BS
There is an issue with registration in Brainstorm, based only on the NAS/LPA/RPA.
I don't know where you put them, but maybe your choice of points makes it much better already.
There is no head surface in the anatomy you posted. The head surface used here is the one reconstructed by Brainstorm, which might be shrunk by 1-2mm.
The template position we distribute with these templates must be projected on the head surface within the template (the brainstorm ones), not the ones you see in Blender.
The order must be fixed.
This image is from the templates downloaded from the Git repo?
Yes.
Loaded using the modified script I posted previously.
