Compute surface maps used for field display in 3D.
Evoked
| Epochs
| Raw
The measurement file. Need to have info attribute.
str
| ‘auto’ | None
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.
str
| None
The subject name corresponding to FreeSurfer environment variable SUBJECT. If None, map for EEG data will not be available.
str
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.
Either 'accurate'
or 'fast'
, determines the quality of the
Legendre polynomial expansion used. 'fast'
should be sufficient
for most applications.
Should be 'helmet'
or 'head'
to specify in which surface
to compute the MEG field map. The default value is 'helmet'
.
Origin of the sphere in the head coordinate frame and in meters.
Can be 'auto'
, which means a head-digitization-based origin
fit. Default is (0., 0., 0.04)
.
New in version 0.11.
int
| None
The number of jobs to run in parallel. If -1
, it is set
to the number of CPU cores. Requires the joblib
package.
None
(default) is a marker for ‘unset’ that will be interpreted
as n_jobs=1
(sequential execution) unless the call is performed under
a joblib.parallel_backend()
context manager that sets another
value for n_jobs
.
str
| list
of str
Head source(s) to use. See the source
option of
mne.get_head_surf()
for more information.
New in version 1.1.
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.
list
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).
