Toolbar
Toolbar is the section at the top of the Workbench Window that contains viewing settings for the structure you are displaying in the Active Tab and access to Workbench functional modes (border drawing, region of interest definition, etc.).

- The sections and options in the Toolbar change according to the type of view selected: Chart View, Montage View, Volume View, All View, and Surface View. The Volume View Toolbar is shown as an example.

- The Toolbar can be hidden or shown using the button at the top right of the Workbench Window or by clicking on Toolbar in the View Menu.
- Tooltips (available by hovering mouse over buttons/elements) are an easy way to see information on the buttons and functions on the Toolbar (or throughout wb_view).

## Montage Toolbar

- Orientation contains buttons to set orthogonal and User-defined views of the brain surface displayed.

- Orthogonal view buttons are labeled: LM (lateral-medial), DV (dorsal-ventral), AP (anterior-posterior).
- Using the Mouse Controls, in Montage view, rotation is mirrored between hemisphere lateral/medial sides and panning moves hemisphere sides together or away from each other.
- The Reset button resets the orientation/zoom to the default.
- Custom Orientation allows one to set and save (or not) a specific transform (pan, rotate, oblique rotate, zoom) for a surface or volume.

- Montage Selection contains pull-downs and checkboxes to set the surface montage to view.

- Top Left pull-down sets the montage structure: Cerebral Cortex, Cerebellar Cortex, or Flat. A structure is only viewable if the appropriate surface is loaded.
- Top Right pull-down sets the page orientation of the surfaces displayed. Pull-downs in the middle set the surface file for each hemisphere from the list of loaded files. Up to 2 left and 2 right surfaces can be displayed at once. The checkboxes indicate if the set surfaces are being displayed.
- Left, Lateral, Medial, and Right checkboxes indicate if these structures are being displayed.

- Mode contains buttons for switching between Viewing Area mouse controls for performing actions including Border drawing and Foci creation or typical View mode.

- Clipping contains settings for cutting down Surface, Volume, or Features data to be viewed.

Tab contains cross-tab functions for yoking the display of two or more Viewing Tabs and for locking aspect ratio (used with annotations). Shading slightly alters the coloring assigned to brainordinates to provide a better quality image. Shading only affects surfaces.

## Volume Toolbar

- Slice Plane contains buttons to set which volume slice planes are displayed: P (parasagittal), C (coronal), A (axial), All (all 3 planes).

> - The Reset button resets the orientation/zoom to the default.

> - Custom Orientation allows one to set and save (or not) a specific transform (pan, rotate, oblique rotate, zoom) for a surface or volume.
> - The crosshair button (large '+' symbol) enables the drawing of crosshairs, representing the selected slices.
> - The crosshair labels button enables drawing labels indicating the orientation of the viewed slice.

- Montage contains settings for viewing multiple volume slices from a single slice plane at once. Rows/Cols set the number of Rows or Columns of slices to display. Step sets the index spacing between slices in the volume slice montage.

- Slice Indices/Coords contains settings for the slice index and stereotaxic (Talairach) coordinate to be viewed for each slice plane.

> - The vertical Origin button rests the slice indices to the default (centered at the AC).

> - The button (default on) activates movement of the crosshairs/volume slice to the same plane as the brainordinate selected in any of the Viewing Tabs in the same yoking group as the Volume tab.

> - The pull-down at the bottom toggles between Orthogonal and Oblique volume viewing.
> - The button at the left enables the slices to move to the brainordinate of an identification operation (mouse click on a volume slice or a surface.
> - The "M" button at the right selects masking during oblique viewing. In oblique viewing, cubic interpolation is used which may cause edge effects and masking will remove these edge effects.

- Mode contains buttons for switching between Viewing Area mouse controls for performing actions including Border drawing and Foci creation or typical View mode.

- Clipping contains settings for cutting down Surface, Volume, or Features data to be viewed.

- Tab contains cross-tab functions for yoking the display of two or more Viewing Tabs and for locking aspect ratio (used with annotations). Shading slightly alters the coloring assigned to brainordinates to provide a better quality image. Shading only affects surfaces.

## All Toolbar

- Orientation contains buttons to set orthogonal and User-defined views of the brain surfaces/volume displayed.

> - To change the structure's surface file, click on the L, R or C button and a list of loaded files will appear for selection.

> - The scroll boxes to the right, control the spacing between left and right hemispheres (relative to anatomical spacing = 0) and the spacing of the cerebellum away from the cortex.

- Slice Indices/Coords contains toggles to turn off/on volume planes (P = parasagittal, C = coronal, A = axial) and settings for the slice index and stereotaxic (Talairach) coordinate to be viewed.

- Edit Label... Pops up a dialog for editing the text in the axis' label.
- Axis Checkbox - Turns display of the entire axis on of off.
- Label Checkbox - Turns display of the label on or off.
- Nums Checkbox - Turns display of the numeric values in the axis on or off.
- Rotate Checkbox - When checked, the label is rotated so that the text is oriented bottom to top (rotated 90 degrees).

Data sets the axis range to the exact range of the data. User allows the user to set the minimum and maximum of the data displayed.
- Max (Range) Value - The minimum value in the axis.

## Line Series Old Chart Toolbar

Chart Type (Old), determines which kind of chart is viewed. If one or more Workbench-chartable files are loaded, one or more Chart Types will be available for selection. Chartable files for the selected Chart Type are listed and can be selected for display in the Overlay Toolbox Charting tab.
Chart Types currently available:
Data/Time Series (top image) chartable files are graphed for a brainordinate identified in a non-Chart view Viewing Tab, showing a data value (y-axis) for each Map Index/unit of time (x-axis). The following file types are available for Data/Time Series charting, as long as they contain more than one map:
* CIFTI Data Series (.dtseries.nii)
* CIFTI Parcel Scalar (.pscalar.nii)
* CIFTI Parcel Series (.ptseries.nii)
* CIFTI Scalar (.dscalar.nii)
* Metric (.func.gii, .shape.gii)
* Volume (.nii, .nii.gz)
Matrix (bottom image) chartable files:
* CIFTI Parcel to parcel connectivity (.pconn.nii) -- matrix with parcels as the y-axis rows, parcels as the x-axis columns, and the colored cells indicate the correlation (connectivity) values between the parcel pair.
* CIFTI Parcel Scalar (.pscalar.nii) -- matrix with parcels as the y-axis rows, map indices as the x-axis columns, and the colored cells indicate the scalar data value for a parcel/map pair in a particular parcel (identified in a non-Chart view Viewing Tab).
