mne.make_forward_solution#
- mne.make_forward_solution(info, trans, src, bem, meg=True, eeg=True, *, mindist=0.0, ignore_ref=False, n_jobs=None, verbose=None)[source]#
Calculate a forward solution for a subject.
- Parameters:
- info
mne.Info
| path-like The
mne.Info
object with information about the sensors and methods of measurement. Ifpath-like
, it should be astr
orpathlib.Path
to a file with measurement information (e.g.mne.io.Raw
).- transpath-like |
dict
| instance ofTransform
|None
If str, the path to the head<->MRI transform
*-trans.fif
file produced during coregistration. Can also be'fsaverage'
to use the built-in fsaverage transformation. If trans is None, an identity matrix is assumed.Changed in version 0.19: Support for
'fsaverage'
argument.- srcpath-like | instance of
SourceSpaces
Either a path to a source space file or a loaded or generated
SourceSpaces
.- bempath-like |
dict
Filename of the BEM (e.g.,
"sample-5120-5120-5120-bem-sol.fif"
) to use, or a loaded sphere model (dict).- meg
bool
If True (Default), include MEG computations.
- eeg
bool
If True (Default), include EEG computations.
- mindist
float
Minimum distance of sources from inner skull surface (in mm).
- ignore_ref
bool
If True, do not include reference channels in compensation. This option should be True for KIT files, since forward computation with reference channels is not currently supported.
- n_jobs
int
|None
The number of jobs to run in parallel. If
-1
, it is set to the number of CPU cores. Requires thejoblib
package.None
(default) is a marker for ‘unset’ that will be interpreted asn_jobs=1
(sequential execution) unless the call is performed under ajoblib.parallel_backend()
context manager that sets another value forn_jobs
.- verbose
bool
|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.

Notes
The
--grad
option from MNE-C (to compute gradients) is not implemented here.To create a fixed-orientation forward solution, use this function followed by
mne.convert_forward_solution()
.Note
If the BEM solution was computed with OpenMEEG in
mne.make_bem_solution()
, then OpenMEEG will automatically be used to compute the forward solution.Changed in version 1.2: Added support for OpenMEEG-based forward solution calculations.
