mne_check_eeg_locations
Overview
mne_check_eeg_locations validates EEG electrode positions in a FIFF measurement file. It checks for undefined (all-zero) locations, duplicate positions (within 1 mm tolerance), and electrodes at unexpected distances from the origin (outside the 50–150 mm range typical for head-surface electrodes).
This is a C++ port of the original MNE-C tool by Matti Hämäläinen.

Checks Performed
- Undefined locations — electrodes with all-zero position coordinates
- Duplicate positions — pairs of electrodes closer than 1 mm
- Distance from origin — electrodes outside the expected 50–150 mm radius from the origin
Example
mne_check_eeg_locations --meas sam-raw.fif
