Hi, I was trying to plot the electrodes with pial from freesurfer directly with python.
I used nibabel to read the lh.pial and rh.pial, then get the coordinates of vertices and the connection. so I can plot the pial brain using some opengl package, like mayavi or pyvista.
Then I plot the SEEG electrodes at the same time.
Coordinates of the brain are in the Freesurfer surface RAS, which is a little different from RAS, so I am not sure if I should transform the world coordinstes to surface ras, and how.
