mne_make_eeg_layout
Overview
mne_make_eeg_layout creates a 2D topographical EEG electrode layout file from the 3D electrode positions stored in a FIFF file.
This is a C++ port of the original MNE-C tool by Matti Hämäläinen.
Usage
mne_make_eeg_layout [options]
Options
| Option | Description |
|---|---|
--fif <name> | FIFF file with EEG channel information (required) |
--out <name> | Output layout file (.lout) (required) |
--width <val> | Channel box width (default: 5.0) |
--height <val> | Channel box height (default: 4.0) |
--help | Print help |
--version | Print version |
Description
This utility extracts EEG electrode positions from a FIFF file and projects them to a 2D plane using azimuthal equidistant projection. The resulting layout file (.lout) can be used by visualization tools to display topographical maps of EEG data.
The width and height parameters control the size of the rectangular box drawn around each channel marker in the layout.
Example
mne_make_eeg_layout --fif raw.fif --out eeg_layout.lout
# With custom box dimensions
mne_make_eeg_layout --fif raw.fif --out eeg_layout.lout --width 3.0 --height 2.5
