mne.read_forward_solution#
- mne.read_forward_solution(fname, include=(), exclude=(), *, ordered=True, verbose=None)[source]#
Read a forward solution a.k.a. lead field.
- Parameters:
- fnamepath-like
The file name, which should end with
-fwd.fif,-fwd.fif.gz,_fwd.fif,_fwd.fif.gz,-fwd.h5, or_fwd.h5.- include
list, optional List of names of channels to include. If empty all channels are included.
- exclude
list, optional List of names of channels to exclude. If empty include all channels.
- orderedbool
If True (default), ensure that the order of the channels in the modified instance matches the order of
ch_names.New in v0.20.0.
Changed in version 1.7: The default changed from False in 1.6 to True in 1.7.
- 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.
- Returns:
- fwdinstance of
Forward The forward solution.
- fwdinstance of

Notes
Forward solutions, which are derived from an original forward solution with free orientation, are always stored on disk as forward solution with free orientation in X/Y/Z RAS coordinates. To apply any transformation to the forward operator (surface orientation, fixed orientation) please apply
convert_forward_solution()after reading the forward solution withread_forward_solution().Forward solutions, which are derived from an original forward solution with fixed orientation, are stored on disk as forward solution with fixed surface-based orientations. Please note that the transformation to surface-based, fixed orientation cannot be reverted after loading the forward solution with
read_forward_solution().
