mne.create_default_subject#
- mne.create_default_subject(fs_home=None, update=False, subjects_dir=None, verbose=None)[source]#
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.
- Parameters:
- fs_home
None
|str
The freesurfer home directory (only needed if
FREESURFER_HOME
is not specified as environment variable).- update
bool
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.
- subjects_dir
None
| path-like Override the
SUBJECTS_DIR
environment variable (os.environ['SUBJECTS_DIR']
) as destination for the new subject.- verbose
bool
|str
|int
|None
Control verbosity of the logging output. If
None
, use the default verbosity level. See the logging documentation andmne.verbose()
for details. Should only be passed as a keyword argument.
- fs_home
Notes
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.
