mne.viz.Brain #

Plot a cortical parcellation

add_data(array, fmin=None, fmid=None, fmax=None, thresh=None, center=None, transparent=False, colormap='auto', alpha=1, vertices=None, smoothing_steps=None, time=None, time_label='auto', colorbar=True, hemi=None, remove_existing=None, time_label_size=None, initial_time=None, scale_factor=None, vector_alpha=None, clim=None, src=None, volume_options=0.4, colorbar_kwargs=None, verbose=None)[source]#

Display data from a numpy array on the surface or volume.

This provides a similar interface to surfer.Brain.add_overlay(), but it displays it with a single colormap. It offers more flexibility over the colormap, and provides a way to display four-dimensional data (i.e., a timecourse) or five-dimensional data (i.e., a vector-valued timecourse).

Note

fmin sets the low end of the colormap, and is separate from thresh (this is a different convention from surfer.Brain.add_overlay()).

Parameters:

arraynumpy array, shape (n_vertices[, 3][, n_times])

Data array. For the data to be understood as vector-valued (3 values per vertex corresponding to X/Y/Z surface RAS), then array must be have all 3 dimensions. If vectors with no time dimension are desired, consider using a singleton (e.g., np.newaxis) to create a “time” dimension and pass time_label=None (vector values are not supported).

fminfloat

Minimum value in colormap (uses real fmin if None).

fmidfloat

Intermediate value in colormap (fmid between fmin and fmax if None).

fmaxfloat

Maximum value in colormap (uses real max if None).

threshNone or float

Not supported yet. If not None, values below thresh will not be visible.

centerfloat or None

If not None, center of a divergent colormap, changes the meaning of fmin, fmax and fmid.

transparentbool | None

If True: use a linear transparency between fmin and fmid and make values below fmin fully transparent (symmetrically for divergent colormaps). None will choose automatically based on colormap type.

colormapstr, list of color, or array

Name of matplotlib colormap to use, a list of matplotlib colors, or a custom look up table (an n x 4 array coded with RBGA values between 0 and 255), the default “auto” chooses a default divergent colormap, if “center” is given (currently “icefire”), otherwise a default sequential colormap (currently “rocket”).

alphafloat in [0, 1]

Alpha level to control opacity of the overlay.

verticesnumpy array

Vertices for which the data is defined (needed if len(data) < nvtx).

smoothing_stepsint or None

Number of smoothing steps (smoothing is used if len(data) < nvtx) The value ‘nearest’ can be used too. None (default) will use as many as necessary to fill the surface.

timenumpy array

Time points in the data array (if data is 2D or 3D).

time_labelstr | callable() | None

Format of the time label (a format string, a function that maps floating point time values to strings, or None for no label). The default is 'auto', which will use time=%0.2f ms if there is more than one time point.

colorbarbool

Whether to add a colorbar to the figure. Can also be a tuple to give the (row, col) index of where to put the colorbar.

hemistr | None

If None, it is assumed to belong to the hemisphere being shown. If two hemispheres are being shown, an error will be thrown.

remove_existingbool

Not supported yet. Remove surface added by previous “add_data” call. Useful for conserving memory when displaying different data in a loop.

time_label_sizeint

Font size of the time label (default 14).

initial_timefloat | None

Time initially shown in the plot. None to use the first time sample (default).

scale_factorfloat | None (default)

The scale factor to use when displaying glyphs for vector-valued data.

vector_alphafloat | None

Alpha level to control opacity of the arrows. Only used for vector-valued data. If None (default), alpha is used.

climdict

Original clim arguments.

srcinstance of SourceSpaces | None

The source space corresponding to the source estimate. Only necessary if the STC is a volume or mixed source estimate.

volume_optionsfloat | dict | None

Options for volumetric source estimate plotting, with key/value pairs:

'resolution'float | None
Resolution (in mm) of volume rendering. Smaller (e.g., 1.) looks better at the cost of speed. None (default) uses the volume source space resolution, which is often something like 7 or 5 mm, without resampling.
'blending'str
Can be “mip” (default) for maximum intensity projection or “composite” for composite blending using alpha values.
'alpha'float | None
Alpha for the volumetric rendering. Defaults are 0.4 for vector source estimates and 1.0 for scalar source estimates.
'surface_alpha'float | None
Alpha for the surface enclosing the volume(s). None (default) will use half the volume alpha. Set to zero to avoid plotting the surface.
'silhouette_alpha'float | None
Alpha for a silhouette along the outside of the volume. None (default) will use 0.25 * surface_alpha.
'silhouette_linewidth'float
The line width to use for the silhouette. Default is 2.

A float input (default 1.) or None will be used for the 'resolution' entry.

colorbar_kwargsdict | None

Options to pass to pyvista.Plotter.add_scalar_bar() (e.g., dict(title_font_size=10)).

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

If the data is defined for a subset of vertices (specified by the “vertices” parameter), a smoothing method is used to interpolate the data onto the high resolution surface. If the data is defined for subsampled version of the surface, smoothing_steps can be set to None, in which case only as many smoothing steps are applied until the whole surface is filled with non-zeros.

Due to a VTK alpha rendering bug, vector_alpha is clamped to be strictly < 1.

hemistr | None: If None, it is assumed to belong to the hemipshere being shown.
subdirNone | str: If a label is specified as name, subdir can be used to indicate that the label file is in a sub-directory of the subject’s label directory rather than in the label directory itself (e.g. for $SUBJECTS_DIR/$SUBJECT/label/aparc/lh.cuneus.label brain.add_label('cuneus', subdir='aparc')).

The movie is created through the imageio module. The format is determined by the extension, and additional options can be specified through keyword arguments that depend on the format, see imageio’s format page.

Warning

This method assumes that time is specified in seconds when adding data. If time is specified in milliseconds this will result in movies 1000 times longer than expected.

Orient camera to display view.

Parameters:

viewstr | None: The name of the view to show (e.g. “lateral”). Other arguments take precedence and modify the camera starting from the view. See Brain.show_view for valid string shortcut options.

'lateral': From the left or right side such that the lateral (outside) surface of the given hemisphere is visible.
'medial': From the left or right side such that the medial (inside) surface of the given hemisphere is visible (at least when in split or single-hemi mode).
'rostral': From the front.
'caudal': From the rear.
'dorsal': From above, with the front of the brain pointing up.
'ventral': From below, with the front of the brain pointing up.
'frontal': From the front and slightly lateral, with the brain slightly tilted forward (yielding a view from slightly above).
'parietal': From the rear and slightly lateral, with the brain slightly tilted backward (yielding a view from slightly above).
'axial': From above with the brain pointing up (same as 'dorsal').
'sagittal': From the right side.
