mne.read_forward_solution¶

mne.read_forward_solution(fname, include=(), exclude=(), verbose=None)[source]¶

Read a forward solution a.k.a. lead field.

Parameters

fnamestr: The file name, which should end with -fwd.fif or -fwd.fif.gz.
includelist, optional: List of names of channels to include. If empty all channels are included.
excludelist, optional: List of names of channels to exclude. If empty include all channels.
verbosebool, str, int, or None: If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

Returns

fwdinstance of Forward: The forward solution.

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 with read_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().
