Overlay ECOG onto one default MRI cortex

[sugata_hisato]

Hi Raymundo,

Thank you for your support.

I successfully imported individual subjects with different ECOG locations in the same protocol.

Now, I want to overlay their ECOG signals onto one default MRI cortex. Do you have any suggestions on how to accomplish this?

Best regards,

Hisato

Are you looking to overlap ECOG sensor locations, rather that signals?

For overlapping sensors, a GUI option is not available yet. However, it can be done, by exporting the sensors locations (in MNI space) for each subject, then concatenating those locations in a new channel file, and use that concatenate channel file for the default anatomy. Check this post:

Hi @HOno, The requirement would be that Subject's individual anatomy has been MNI-normalized. The aggregation of electrodes is not done automatically, but all the data that is needed is there. The steps to follow are: Create a Subject to aggregate all the electrodes (CoReg Subject) Create a new Subject: Default anatomy NO, Default channel file NO In the Anatomy view, right-click on the Subject > Use Template > FsAverage > FsAverage_2020 For each of the Subjects Right click their C…

For overlapping signals, can you provide an example of the expected result?

I plan to combine both individual ECOG locations and signals. I will send some example data to your personal email.

I understand that. I will be careful in the future.
