- mne.create_default_subject(fs_home=None, update=False, subjects_dir=None, verbose=None)¶
Create an average brain subject for subjects without structural MRI.
Create a copy of fsaverage from the Freesurfer directory in subjects_dir and add auxiliary files from the mne package.
The freesurfer home directory (only needed if FREESURFER_HOME is not specified as environment variable).
In cases where a copy of the fsaverage brain already exists in the subjects_dir, this option allows to only copy files that don’t already exist in the fsaverage directory.
Override the SUBJECTS_DIR environment variable (os.environ[‘SUBJECTS_DIR’]) as destination for the new subject.
- verbosebool |
When no structural MRI is available for a subject, an average brain can be substituted. Freesurfer comes with such an average brain model, and MNE comes with some auxiliary files which make coregistration easier.
create_default_subject()copies the relevant files from Freesurfer into the current subjects_dir, and also adds the auxiliary files provided by MNE.
