You can create a point set. I would recommend creating an initial point set in freeview, saving it (json), then looking at that to get the format, then create a new json with your points. If you have them as a binary map in nifti, you can load that with your anatomical (assuming the nifti volume has the proper geometry), then view as a segmentation, then show the segmentation as an isosurface in 3d (you'll probably want to voxelize it).

External Email - Use Caution

Hi,

I have completed the Freesurfer segmentation and parcellation in a patient that has intracranial electrodes.

I also have the electrode locations in various file formats (tsv, nii and pom).

Is there a way to visualize their location in Freeview and particularly in 3D?

For example, for 2D I can easily do that with microGL.

Thank you very much in advance!

Best,

Panos Kerezoudis
