mne.get_meg_helmet_surf

mne.get_meg_helmet_surf(info, trans=None, verbose=None)[source]

Load the MEG helmet associated with the MEG sensors.

Parameters:
info : instance of Info

Measurement info.

trans : dict

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.

verbose : bool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more).

Returns:
surf : dict

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.
