mne.datasets.fetch_fsaverage

mne.datasets.fetch_fsaverage(subjects_dir=None, verbose=None)

Fetch and update fsaverage.

Parameters

subjects_dirstr | None

The path to use as the subjects directory in the MNE-Python config file. None will use the existing config variable (i.e., will not change anything), and if it does not exist, will use ~/mne_data/MNE-fsaverage-data.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns

fs_dirstr

The fsaverage directory. (essentially subjects_dir + '/fsaverage').

Notes

This function is designed to provide

1. All modern (Freesurfer 6) fsaverage subject files

2. All MNE fsaverage parcellations

3. fsaverage head surface, fiducials, head<->MRI trans, 1- and 3-layer BEMs (and surfaces)

This function will compare the contents of subjects_dir/fsaverage to the ones provided in the remote zip file. If any are missing, the zip file is downloaded and files are updated. No files will be overwritten.

New in version 0.18.
