mne.get_meg_helmet_surf

mne.get_meg_helmet_surf(info, trans=None, verbose=None)

Load the MEG helmet associated with the MEG sensors.

Parameters:

infomne.Info

The mne.Info object with information about the sensors and methods of measurement.

transdict

The head<->MRI transformation, usually obtained using read_trans(). Can be None, in which case the surface will be in head coordinates instead of MRI coordinates.

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:

surfdict

The MEG helmet as a surface.

Notes

A built-in helmet is loaded if possible. If not, a helmet surface will be approximated based on the sensor locations.
