Compute surface maps used for field display in 3D.
The measurement file. Need to have info attribute.
str| ‘auto’ |
The full path to the
*-trans.fif file produced during
coregistration. If present or found using ‘auto’
the maps will be in MRI coordinates.
If None, map for EEG data will not be available.
The subject name corresponding to FreeSurfer environment variable SUBJECT. If None, map for EEG data will not be available.
The path to the freesurfer subjects reconstructions. It corresponds to Freesurfer environment variable SUBJECTS_DIR.
None| ‘eeg’ | ‘meg’
If None, a map for each available channel type will be returned. Else only the specified type will be used.
'fast', determines the quality of the
Legendre polynomial expansion used.
'fast' should be sufficient
for most applications.
'head' to specify in which surface
to compute the MEG field map. The default value is
Origin of the sphere in the head coordinate frame and in meters.
'auto', which means a head-digitization-based origin
fit. Default is
(0., 0., 0.04).
New in version 0.11.
The number of jobs to run in parallel. If
-1, it is set
to the number of CPU cores. Requires the
None (default) is a marker for ‘unset’ that will be interpreted
n_jobs=1 (sequential execution) unless the call is performed under
joblib.parallel_backend() context manager that sets another
Head source(s) to use. See the
source option of
mne.get_head_surf() for more information.
New in version 1.1.
The surface maps to be used for field plots. The list contains separate ones for MEG and EEG (if both MEG and EEG are present).
