mne_list_source_space
Overview
mne_list_source_space lists the contents of a source space FIFF file. It can output source locations in various formats suitable for visualization tools such as MRIlab or text processing.
This is a C++ port of the original MNE-C tool by Matti Hämäläinen.
Usage
mne_list_source_space [options]
Options
| Option | Description |
|---|---|
--src <file> | Source space FIFF file |
--pnt <file> | Output point file (MRIlab format) |
--dip <file> | Output dipole file (MRIlab format) |
--vert <file> | Output vertex file (text) |
--all | List all vertices (not just active) |
--coord <name> | Coordinate frame: head or mri (default: mri) |
--help | Print help |
--version | Print version |
Description
This tool reads a source space from a FIFF file created by mne_make_source_space and outputs the source point locations in the requested format. By default, only active (selected) source points are listed; use --all to include decimated vertices as well.
Workflow Context
mne_list_source_space is useful for verifying source space configurations before computing forward solutions. The output files can be loaded into visualization tools to check that source points are correctly distributed on the cortical surface.
Example
# List active source points as text
mne_list_source_space --src my_source_space-src.fif --vert sources.txt
# Export all vertices in head coordinates
mne_list_source_space --src my_source_space-src.fif --pnt sources.pnt --all --coord head
