[FieldTrip] need for advice on 3D electrode localization

[Julian Keil]

Dear Emmanuelle,

we have a polhemus patriot in our lab which we use in combination with brainstorm (https://neuroimage.usc.edu/brainstorm/ <https://neuroimage.usc.edu/brainstorm/>).
After getting used to the setup, it works quite well and we routinely use it for electrode localization and individual source analyses.

We haven’t done a formal comparison between source analysis accuracy for different combinations of standard MRI, individual MRI, standard electrode positions and individual electrode positions, but since recording the electrodes does not take too much time (10-15 Minutes), we do it routinely.

Let me know if you have any questions regarding the use or setup.

Cheers,

Julian
