[FieldTrip] coregister EEG MRI from concurrent recording

[Steffen Bollmann]

Dear Christine,

I have the same problem, but haven't found a very fast and easy way to do
this.

However, I found a tool, which helps a lot:
http://pylocator.thorstenkranz.de/

Maybe anyone else has better ways of doing it and could share his thoughts?
All the best
Steffen
