Grids and Strips Electrode Localization Utility (gselu)

This is a GUI utility to assist in preprocessing tasks for electrocorticography (ecog) and stereo eeg (seeg) data analysis. It includes:

1. CT-to-MRI co-registration using Mutual Information (via Freesurfer)
2. Automatic electrode extraction and sorting into grids via pre-defined grid geometries
3. A GUI for manually tweaking electrode locations and grid information
4. Snapping electrode locations to a freesurfer cortical surface model
5. Exporting to montage files suitable for use in MNE-python

Dependencies

• A scientific python distribution such as anaconda or canopy
• pysurfer
• nibabel
• mne-python
• pymcubes

Note - you can easily install these dependencies with tools such as pip and easy-install.
