mne.SourceSpaces#

class mne.SourceSpaces(source_spaces, info=None)[source]#

infodict: Dictionary with information about the creation of the source space file. Has keys ‘working_dir’ and ‘command_line’.

Attributes

infodict: Dictionary with information about the creation of the source space file. Has keys ‘working_dir’ and ‘command_line’.

__add__(other)[source]#: Combine source spaces.

__contains__(key, /)#: Return key in self.

__getitem__(*args, **kwargs)[source]#: Get an item.

__iter__(/)#: Implement iter(self).

__len__(/)#: Return len(self).

__mul__(value, /)#: Return self*value.

append(object, /)#: Append object to the end of the list.

clear(/)#: Remove all items from list.

copy()[source]#

Make a copy of the source spaces.

Returns

srcinstance of SourceSpaces: The copied source spaces.

count(value, /)#: Return number of occurrences of value.

export_volume(fname, include_surfaces=True, include_discrete=True, dest='mri', trans=None, mri_resolution=False, use_lut=True, overwrite=False, verbose=None)[source]#

Export source spaces to nifti or mgz file.

Parameters

fnamestr: Name of nifti or mgz file to write.
include_surfacesbool: If True, include surface source spaces.
include_discretebool: If True, include discrete source spaces.
dest‘mri’ | ‘surf’: If ‘mri’ the volume is defined in the coordinate system of the original T1 image. If ‘surf’ the coordinate system of the FreeSurfer surface is used (Surface RAS).
transdict, str, or None: Either a transformation filename (usually made using mne_analyze) or an info dict (usually opened using read_trans()). If string, an ending of .fif or .fif.gz will be assumed to be in FIF format, any other ending will be assumed to be a text file with a 4x4 transformation matrix (like the --trans MNE-C option. Must be provided if source spaces are in head coordinates and include_surfaces and mri_resolution are True.
mri_resolutionbool | str: If True, the image is saved in MRI resolution (e.g. 256 x 256 x 256), and each source region (surface or segmentation volume) filled in completely. If “sparse”, only a single voxel in the high-resolution MRI is filled in for each source point.

Changed in version 0.21.0: Support for “sparse” was added.
use_lutbool: If True, assigns a numeric value to each source space that corresponds to a color on the freesurfer lookup table.
overwritebool: If True (default False), overwrite the destination file if it exists.

New in version 0.19.
verbosebool | 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.

Notes

This method requires nibabel.

Examples using export_volume:

Compute MNE inverse solution on evoked data with a mixed source space

extend(iterable, /)#: Extend list by appending elements from the iterable.

index(value, start=0, stop=sys.maxsize, /)#

Return first index of value.

Raises ValueError if the value is not present.

insert(index, object, /)#: Insert object before index.

plot(head=False, brain=None, skull=None, subjects_dir=None, trans=None, verbose=None)[source]#

Plot the source space.

Parameters

headbool: If True, show head surface.
brainbool | str: If True, show the brain surfaces. Can also be a str for surface type (e.g., ‘pial’, same as True). Default is None, which means ‘white’ for surface source spaces and False otherwise.
skullbool | str | list of str | list of dict | None: Whether to plot skull surface. If string, common choices would be ‘inner_skull’, or ‘outer_skull’. Can also be a list to plot multiple skull surfaces. If a list of dicts, each dict must contain the complete surface info (such as you get from mne.make_bem_model()). True is an alias of ‘outer_skull’. The subjects bem and bem/flash folders are searched for the ‘surf’ files. Defaults to None, which is False for surface source spaces, and True otherwise.
subjects_dirstr | None: Path to SUBJECTS_DIR if it is not set in the environment.
transstr | ‘auto’ | dict | None: The full path to the head<->MRI transform *-trans.fif file produced during coregistration. If trans is None, an identity matrix is assumed. This is only needed when the source space is in head coordinates.
verbosebool | 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.

Returns

figinstance of Figure3D: The figure.

Examples using plot:

Compute MNE inverse solution on evoked data with a mixed source space

pop(index=- 1, /)#

Remove and return item at index (default last).

Raises IndexError if list is empty or index is out of range.

remove(value, /)#

Remove first occurrence of value.

Raises ValueError if the value is not present.

reverse(/)#: Reverse IN PLACE.

save(fname, overwrite=False, *, verbose=None)[source]#

Save the source spaces to a fif file.

Parameters

fnamestr: File to write.
overwritebool: If True (default False), overwrite the destination file if it exists.
verbosebool | 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.
