[FieldTrip] post-op MRI in ECoG

[Arjen Stolk]

Hi Asieh,

The short answer would be yes, as long as you can see the electrodes (voids) in the post-op MR. From the top of my head, you’ll have to specify cfg.magtype = ‘trough’ at step 17 of the iEEG tutorial (http://www.fieldtriptoolbox.org/tutorial/human_ecog). The article linked to this tutorial contains further recommendations for going this route. 

Best,
Arjen

In that case, can fieldtrip be used for electrode localization? If not, is there any other toolbox or software that you recommend for this.
