Set up a custom scene using the FSLeyes API via a custom Python script.
The scene consists of two Ortho views at the top, and one time series at the bottom. I used it to draw a mask to compute velocity encoding. The velocity image and the overlaid mask are shown on the left and the anatomical image on the right.
$ fsleyes -S -r custom_fsleyes_scene_timeseries.py <VELOCITY> <ANAT> <MASK># Show two OrthoPanels next to each other
ortho_left = frame.addViewPanel(OrthoPanel)
ortho_left.defaultLayout()
ortho_right = frame.addViewPanel(OrthoPanel)
ortho_right.defaultLayout()
# Show one TimeSeriesPanels at the bottom
timeseriespanel_bottom = frame.addViewPanel(TimeSeriesPanel)
timeseriespanel_bottom.defaultLayout()
# Keep only axial plane for the ortho_left
ortho_left.sceneOpts.showXCanvas = False
ortho_left.sceneOpts.showYCanvas = False
# Keep only axial plane for the ortho_right
ortho_right.sceneOpts.showXCanvas = False
ortho_right.sceneOpts.showYCanvas = False
# Get list of loaded overlays based on the files listed in the command line
velocity, anat, mask = overlayList
# Get Display objects for each image and for each view
velocity_leftdisplay = ortho_left.displayCtx.getDisplay(velocity)

velocity_timeseriespanel = timeseriespanel_bottom.displayCtx.getDisplay(velocity)
