GNU General Public License v3 Yes University of Oslo - CONICET Argentina NITRC iElectrodes OS Independent MATLAB iElectrodes is an open source toolbox to semiautomatically localize and label intracranial electrodes in 2-3 minutes. The toolbox precisely localizes subdural grids (ECoG) and depth (SEEG) electrodes using MRI and CT images. 2D and 3D visualization simplify the comprehension of anatomical locations. Also, it is possible to add anatomical information (brain parcellation images) and surfaces from Freesurfer. Data can be exported in multiple formats, including EEGLAB and Fieldtrip. Additionally, grid electrodes can be corrected for brain shift or compression effects, and projected to brain surface. Planning of depth electrode implantation is fast and easy.
