mne.get_meg_helmet_surf#
- mne.get_meg_helmet_surf(info, trans=None, *, upsampling=1, verbose=None)[source]#
Load the MEG helmet associated with the MEG sensors.
- Parameters:
- info
mne.Info The
mne.Infoobject with information about the sensors and methods of measurement.- 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.
- upsampling
int The upsampling factor to use for the helmet mesh. The default (1) does no upsampling. Larger integers lead to more densely sampled helmet surfaces, and the number of vertices increases as a factor of
4**(upsampling-1).- verbosebool |
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.
- info
- Returns:
- surf
dict The MEG helmet as a surface.
- surf
Notes
A built-in helmet is loaded if possible. If not, a helmet surface will be approximated based on the sensor locations.
