|}
Slicer4's main desktop interface provides top-level access to most commonly-used features, and organizes them into logical groupings. These groups of features are presented in a number of interface panels on the GUI, as is illustrated in the basic layout below. The interface is designed to be easy to learn and remember, to ease navigation of Slicer's large (and growing) functionality, and to easily collapse and hide when you don't need to see it.

==Application Menu==

Slicer's Application Menu contains many useful features. A brief overview of some of these is given below.

*File Menu
**The File Menu contains options for loading a MRML scene, for downloading sample datasets from the internet, or individual datasets of various types. An option for saving scenes and data is also provided here.
*Edit Menu
**The Edit menu contains an option to raise the [[Documentation/{{documentation/version}}/SlicerApplication/ApplicationSettings|Application Settings Interface]]. This interface allows users to customize their installation of Slicer. '''Edit->Application Settings'' can be used to include or suppress various Slicer modules, to customize the appearance of your Python Interactor, to select a custom font, to specify a temporary directory, and to accomplish other customizations as well.
*View Menu
**This menu contains options to raise the Python Interactor and the [[Documentation/{{documentation/version}}/SlicerApplication/ErrorLog|Error Log]], both useful developer tools. Menu options to switch layouts, and to toggle the display of individual toolbars and the module GUI panels are also provided under the View Menu.

[[image: Slicer4AppMenu.jpg | center]]

==Toolbar==

The Toolbar provides shortcuts to many useful sets of functionality. The following toolbars appear here by default. Customization is possible from the Slicer View Menu.

===Load & Save Options===
The '''Load Scene''' option will raise a browser to select and load a collection of data as a MRML scene. This option clears the existing scene and resets the application state. The '''Save''' option will raise the "Save Data" Interface which offers a variety of options for saving MRML scenes and individual datasets.
===Module Selection & Navigation===
The Module Selection & Navigation toolbar provides options for searching for module names, selecting from a module menu, and moving backward and forward through the module selection history for convenience.
===Core Modules===
The Core Module Toolbar provides shortcuts to your "Home" module, and some of Slicer's core modules including
* Models
* Transforms
* Data
* Volumes
* Annotations
* Interactive Editor
===Layouts===
The Layout Toolbar provides a drop-down menu of layouts useful for many types of studies. When Slicer is exited normally, the selected layout is saved and restored as part of the Application state.
[[image:Slicer4Layouts.jpg | center]]
===Mouse Modes===
[[image:Slicer4MouseModeToolbar.jpg | center]]
Slicer has two mouse modes: '''Transform''' (which allows interactive rotate, translate and zoom operations), and '''Place''' (which permits objects to be interactively placed in 3D or 2D). The toolbar icons that switch between these mouse modes are shown from left to right above, respectively. '''Place Fiducial''' is the default place option as shown above; options to place both '''Ruler''' and '''Region of Interest''' Widgets are also available from the drop-down Place Mode menu.
'''Hint: Transform''' mode is the default interaction mode. By default, '''Place''' mode persists for one "place" operation after the Place Mode icon is selected, and then the mode switches back to Transform. Place mode can be made persistent (useful for creating multiple fiducial points, rulers, etc.) by checking the '''Persistent''' checkbox shown rightmost in the Mouse Mode Toolbar.
===Screenshots & Scene Views===
[[image:Slicer4CaptureToolbar.png | center]]
This toolbar presents options for capturing screenshots (1st icon) and '''Scene Views''' (2nd icon) and restoring saved scene views (3rd icon). A Scene View is a description of the state of the MRML scene at the time of its capture that can be restored at any time. This mechanism is useful for preparing and viewing multiple interesting presentations of a complicated dataset. More information in the [[Documentation/{{documentation/version}}/Modules/SceneViews|Scene Views module]].
===Crosshair Options===
The Crosshair Toolbar provides a set of options for customizing the appearance and behavior of the crosshairs across all Slice Viewers.
[[ image:Slicer4CrosshairOptions.jpg | center]]

==Module Panel==

Any selected module in Slicer will display its user interface in the '''Module Panel'''. The panel may be undocked (by left-clicking & dragging the panel chrome or by selecting its undock icon; hidden by selecting the hide (X) icon, or have its display toggled by selecting View->Module Panel. The panel can be re-docked by double-clicking on its chrome.

==Data Probe==

The Data Probe interactively reports data values at voxels indexed by the current mouse position in all layers (Label, Foreground and Background).

See the [[Documentation/{{documentation/version}}/Modules/DataProbe|Data Probe documentation]] for more information about the data values displayed.

== 3D Viewer ==

Access the 3D Viewer Controller by mousing over the '''push-pin''' icon in the top left corner of any 3D Viewer. The panel may be opened persistently by clicking the push-pin icon which effectively "pins" it open. Clicking again "unpins" the panel. Next to the push-pin, a unique ID may be found that distinguishes this 3D viewer from other 3D viewers that may have been created when other layouts were selected. The panel contains options for setting the viewpoint direction, and configuring the appearance and behavior of any 3D Viewer.

[[image:Slicer43DViewController.jpg | center ]]

== Slice Viewers ==

Access any Slice Viewer's Controller by mousing over its '''push-pin''' icon in the top left corner of any slice viewer. The panel may also be opened persistently by clicking the push-pin icon. Next to the push-pin a unique ID may be found that distinguishes the particular Slice Viewer from other Slice Viewers that may have been created when other layouts were selected. A '''Slice Scrollbar''' is provided for manually sweeping through slices and a slice number entry widget is also provided at the top right of the display for manually indexing a particular slice. Each Slice Viewer contains options for displaying each of the layers (Foreground, Background and Label). For the Foreground and Label layers, the opacity of the layer can be controlled by using the spinbox opacity widget (pointed by the "Opacity" annotation in the figure below). In addition, the visibility of the Label layer can be toggled between the "contour" and "solid" mode (see "Label contour" button in the diagram below).

Some Slice Viewer configuration options may be applied to '''one or all''' Slice Viewers by using the '''Link''' option. When viewers are unlinked, an option applies only to the viewer being adjusted. When viewers are linked, the option will apply to '''all''' Slice Viewers. Link and Unlink are persistent settings, and the additional '''Hot-Link''' option available from the pull-down menu applies only for one mouse operation.

[[image:SliceViewerController-4.1.png | center]]

== Chart Viewers ==

Access any Chart Viewer's Controller by mousing over its '''push-pin''' icon in the top left corner of any chart viewer. The panel may also be opened persistently by clicking the push-pin icon. Next to the push-pin a unique ID may be found that distinguishes the particular Chart Viewer from other Chart Viewers that may have been created when other layouts were selected. Each Chart Viewer contains options for controlling the content and display of a Chart.

The content and display of a Chart is controlled by selecting a specific Chart for the Chart Viewer. A Chart Viewer can switch between multiple Charts by selecting different Charts from the Scene. The type of the chart can '''Line''', '''Bar''', or '''Scatter'''. The style can be modified by toggling the display of '''Lines''' and '''Markers''' for the data or by toggling the display of a '''Grid''' or the '''Legend'''. The content of the Chart can be modified by adding and removing individual '''Arrays''' from the Chart. The Chart's '''Title''', '''X-axis Label''', and '''Y-axis Label''' can be edited using the controls in the Chart Viewer's Controller.

== Mouse & Keyboard Across Platforms ==

Below is basic information about how to use the three-, two-, and one-button mouse (or trackpad) on
Windows, Mac, and Linux platforms to perform basic interaction operations in Slicer.

===Adjusting Window & Level on All Platforms===

Left-clicking and dragging the mouse in any Slice viewer is a quick way to adjust Window and Level. Adjust the middle value (level) of the greyscale window by moving the mouse up (increase level) or down (decrease level), and adjust the greyscale window size by moving the mouse to the left (decrease window size) or right (increase window size). Slicer's '''Volumes Module''' provides a "Display" interface panel for making more precise adjustments.

===Selecting & Manipulating on All Platforms ===

Mousing over any "pickable" object in any of Slicer's viewers will cause the cursor to change from a "pointer"
into a "picking hand". When the cursor shows a picking hand, left-clicking and dragging the mouse will pick and
manipulate the object. Releasing the mouse button will deselect the object.

===Viewer Cross-Reference on All Platforms ===

Holding down the '''Shift-Key''' while moving the mouse in any Slice Viewer will cause other
Slice Viewers to interactively scroll to the same RAS position indexed by the mouse. This feature
is useful when inspecting multiple registered studies.

===Zoom In & Out in Slice & 3D Viewers ===

* '''Windows, Mac & Linux''' with
** '''3-Button Mouse:''' Right-click & drag down & up
** '''2-Button Mouse:''' Right-click & drag down & up
** '''1-Button Mouse:''' Ctrl+Left-click & drag down & up
* '''Mac with trackpad''': two-finger click & drag

===Pan (Translate) in Slicer & 3D Viewers ===

* '''Windows, Mac & Linux''' with
** '''3-Button Mouse:''' Middle-click & drag
** '''2-Button Mouse:''' Shift+Left-click & drag
** '''1-Button Mouse:''' Shift+Left-click & drag

===Rotate in 3D Viewers ===

* '''Windows, Mac & Linux''' with
** '''3-Button Mouse:''' Left-click & drag
** '''2-Button Mouse:''' Left-click & drag
** '''1-Button Mouse:''' Left-click & drag

=F.A.Q.=
=== How to overlay 2 volumes ?===
# [[Documentation/{{documentation/version}}/SlicerApplication/LoadingData|Load]] the two volumes
# Use the [[Documentation/{{documentation/version}}/SlicerApplication/MainApplicationGUI#Slice_Viewers|slice viewer controls]] to select one of the volumes as the foreground and one as the background.
# Change the opacity of the Foreground to your liking.
# If you click on the link symbol, this happens to all viewers

 ===Load & Save Options===
 *The '''[[Documentation/{{documentation/version}}/SlicerApplication/LoadingData|Load Data]]''' icon will open a browser window which allows to select and load individual data elements such as volume and vtk models or entire scenes. This version of load clears the existing scene and resets the application state.
 *The Save option will  open  the '''[[Documentation/{{documentation/version}}/SlicerApplication/SavingData|Save Data]]''' Interface which offers a variety of options for saving MRML scenes, individual datasets and Medical Reality Bundle (.MRB) file.
 **Note: .mrb file is a archive file that contains the mrml scene file and all data for loading into Slicer4. The .mrb file is actually a .zip file but with a different file extension. So, if you rename archive.mrb to be archive.zip you can look at (or modify) the contents using normal tools. The code in slicer that handles reading .mrb files performs an unzip into a temp directory and then reads the first .mrml file it finds there. Because of this, for several of the older .zip files it's possible to open them directly in slicer by just changing the file extension from .zip to .mrb.
