mne.get_head_surf(subject, source=('bem', 'head'), subjects_dir=None, on_defects='raise', verbose=None)[source]#

Load the subject head surface.


Subject name.

sourcestr | list of str

Type to load. Common choices would be 'bem' or 'head'. We first try loading '$SUBJECTS_DIR/$SUBJECT/bem/$SUBJECT-$SOURCE.fif', and then look for '$SUBJECT*$SOURCE.fif' in the same directory by going through all files matching the pattern. The head surface will be read from the first file containing a head surface. Can also be a list to try multiple strings.

subjects_dirpath-like | None

Path to the SUBJECTS_DIR. If None, the path is obtained by using the environment variable SUBJECTS_DIR.

on_defects‘raise’ | ‘warn’ | ‘ignore’

What to do if the surface is found to have topological defects. Can be 'raise' (default) to raise an error, 'warn' to emit a warning, or 'ignore' to ignore when one or more defects are found. Note that a lot of computations in MNE-Python assume the surfaces to be topologically correct, topological defects may still make other computations (e.g., mne.make_bem_model and mne.make_bem_solution) fail irrespective of this parameter.

New in v1.0.

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.
