While in principle all functions can be reached via the mouse (using menu items or clicking buttons), it is often “faster” to use keyboard shortcuts. Below is a list of key bindings to function calls:

To follow this page, you need to have the GUI open by entering neuroelf_gui at the Matlab prompt.

The GUI (and its satellite windows) have the following properties (which can, in part, be manipulated via keyboard commmands):

• for the slicing view:
  • orientation (either neurological or radiological)
  • current view (either 3-panel or one of sagittal-, coronal-, or axial-only views)
  • current position (the X-/Y-/Z- coordinate at which the slicing planes are defined)
  • current volume (or timepoint) of 4D data (fixed at 1 when a 3D dataset is displayed)
  • crosshair display (on or off)
  • currently selected anatomical dataset/object (first dataset dropdown)
  • currently selected statistical dataset/object (second dataset dropdown)
  • currently selected maps from the statistical object (listbox of available maps)
  • statistics settings (tails, value-based thresholding, cluster thresholding on or off, transparency setting, joining or overpainting)
  • interpolation setting (on or off, type of interpolation either linear or cubic)
  • drawing mode (on or off, intensity or undo drawing, drawing-over range definition, brush size and shape, as well as 2D or 3D drawing; VMR/HDR only)
  • potentially linked GLM beta plotter UIs
• for the surface view
  • viewpoint settings (as defined by azimuth and zenith angles, as well as X- and Y- translation along the viewing plane and a scaling factor)
  • currently shown surface objects (scenery listbox)
  • for each shown surface object the currently selected statistical object (configurable on the currently selected surface object only)
  • for each selected statistical object the currently selected maps
  • statistics setting (tails, value-based thresholding, surface cluster size thresholding on or off, transparency setting)
  • for each shown surface object a setup definition (faces or wireframe, transformation)

• orientation - O: toggle between neurological and radiological viewing mode
• current view - T: cycle through the 4 view types (3-panel, sagittal, coronal, axial)
• current position
  • cursor -left/-right: alter current position by decreasing (cursor-left) or increasing (cursor-right) the X-coordinate by 1mm (for 0.5mm-resolution VMRs: 0.5mm), thus altering the sagittal slice view
  • cursor -up/-down: alter current position by increasing (cursor-up) or decreasing (cursor-down) the Z-coordinate by 1mm (for 0.5mm-resolution VMRs: 0.5mm), thus altering the axial slice view
  • SHIFT + cursor -up/-down: alter current position by increasing (cursor-up) or decreasing (cursor-down) the Y-coordinate by 1mm (for 0.5mm-resolution VMRs: 0.5mm), thus altering the coronal slice view
• current volume - SHIFT + cursor -left/-right: decrease (cursor-left) or increase (cursor-right) current volume by 1
• crosshair display - A: toggle crosshair display between on and off
• currently selected dataset - CTRL + S: select next available dataset for display (in the order they are listed in the dropdown)
• currently selected map - SHIFT + M: select next available map from container (only works if exactly one map is selected)
• statistics settings
  • 1/2: en-/ disable positive (1) and negative (2) tail of the currently selected (single) voxel-based map
  • C/K: toggle cluster-size based (k-) thresholding between on and off
  • J: toggle between map-joining and map-overpainting mode (if joined colors will be mixed, otherwise maps appearing later in the list have precedence over earlier maps)
  • N: negate alpha (transparency) value setting (in effect toggling the alpha-by-stats-value scaling between on and off)
  • ALT + cursor -up/-down: increase (cursor-up) or decrease (cursor-down) alpha setting value by 0.1, if value is negative, scale transparency by statistical value
• interpolation
  • I: toggle interpolation setting between on and off
  • M: toggle interpolation mode between linear and cubic
• drawing mode
  • B: switch drawing off (browse-mode)
  • D/3: switch drawing on and enable 2D (D) or 3D (3) drawing mode (within selected slice only)
  • U: toggle between regular (intensity value) and undo (from-buffer) drawing modes

• viewpoint
  • cursor -left/-right: increase (cursor-left, left-rotate) or decrease (cursor-right, right-rotate) azimuth angle of viewpoint by 5 degrees (between 0 and 360)
  • cursor -up/-down: decrease (cursor-up, up-rotate) or increase (cursor-down, down-rotate) zenith angle of viewpoint by 5 degrees (up to +/- 90)
  • SHIFT + cursor -left/-right: decrease (cursor-left, shift-left) or increase (cursor-right, shift-right) X-translation of viewpoint by 5mm (unrestricted)
  • SHIFT + cursor -up/-down: increase (cursor-up, shift-up) or decrease (cursor-down, shift-down) Y-translation of viewpoint by 5mm (unrestricted)
  • CTRL + cursor -up/-down: increase (cursor-up, zoom) or decrease (cursor-down, unzoom) scaling/zoom factor by factor 0.01 (unrestricted)
• currently selected map - SHIFT + M: select next available map from container (only works if exactly one map is selected)
• statistics settings
  • 1/2: en-/ disable positive (1) and negative (2) tail of the currently selected (single) voxel-based map
  • C/K: toggle cluster-size based (k-) thresholding between on and off
  • J: toggle between map-joining and map-overpainting mode (if joined colors will be mixed, otherwise maps appearing later in the list have precedence over earlier maps)

• L: toggle between local-maximum splitting setting on and off (when using the Clustertable button)
• R: reset viewmode (orientation to neurological, current position to 0, 0, 0; interpolation method to cubic, painting mode to regular, viewpoint to default settings, stats transparency alpha to 1)
• S: toggle between full-size and reduced-size modes
• X: toggle between auto-cluster extraction modes on and off (if on, selecting a cluster from the list of VOIs will automatically extract betas from a selected GLM)
• Z: toggle between zoomed and un-zoomed view (in the slicing views)
• CTRL + L: toggle between linked and un-linked browsing

Orientation, current view, current position/viewpoint, current volume, crosshair display, currently selected map, interpolation and across-window-linking can be configured as with the main UI. Additionally, the following keyboard shortcuts are available:

• SHIFT + S: save a screenshot as either BMP, JPG, PNG, or EPS (for high-quality images, particularly for surfaces, e.g. via Photoshop or GIMP rendering)

This list does not contain cursor commands!

• A: toggle crosshair display between on and off (main UI and satellites, slicing view only)
• B: switch drawing off (browse-mode) (main UI only, slicing view only)
• C: toggle cluster-size based (k-) thresholding between on and off (main UI only, slicing and surface views)
