Active tab is the currently selected viewing tab at the top of the Workbench Window. The Overlay and Features Toolboxes provide options for viewing that apply only to the Active tab.

Brainordinate is a brain location that can be specified by a surface vertex (node) or a volume voxel. Brainordinates include grayordinates (gray-matter vertices or voxels) and whiteordinates (white matter voxels). CIFTI files (see below) contain a list of brainordinates and can handle combined surface/volume representations.

Dense Connectome refers to connectivity matrix files that contain correlations between every surface or volume brainordinate and every other surface or volume ordinate in our model of the brain. These files are REALLY big (~30 GB for current resolution). Therefore, they are kept in the HCP database ConnectomeDB, which can access these large files as needed to view connectivity maps of interest. Dense connectomes can also be asymmetric, such as a structural connectivity matrix between grayordinates (all gray matter strucures) and whiteordinates (all white matter structures).

Features Toolboxrefers to the section of the Workbench Window that allows the user to select and set display attributes for Features such as Borders and Foci in the current Active Viewing tab.

GIFTI file is a file format for surface representations that is supported by all major brain mapping visualization platforms (http://www.nitrc.org/projects/gifti).

NIFTI file (*.nii and *nii.gz) is a standard file format for volumetric data that is widely used in neuroimaging. The original NIFTI-1 file format was based on 16-bit signed integers and was limited to 32,767 in each dimension. The NIFTI-2 format (http://www.nitrc.org/forum/message.php?msg_id=3738) is based on 64-bit integers and can handle very large volumes and matrices.

Parcellation refers to the division of the cerebral cortex and subcortical volume into regions that share functional or structural properties.

Specification File (commonly called “Spec File”) is a file used to organize a set of data files (such as volume, label, and metric files) to be loaded into Workbench.

Splash Screen is the first window that opens upon launching Workbench that serves as a title page and shortcut for opening Spec files. It contains a list of Spec files in your current path and those that have been recently opened that can be selected and opened in one step. It also contains links to the HCP website and Twitter feed.

Surface Montage is a viewing mode in which lateral and medial views of both left and right hemispheres are shown in a single viewing area and can be rotated in tandem for a full surface view of the brain.

Tab Montage is a setting that displays the images from all of the tabs you have open in the current Workbench Window in one Viewing Area. All the surfaces and/or volumes displayed in Tab Montage can still be manipulated with the mouse controls (rotate, zoom, pan). This option allows you to view and compare multiple structures and datasets at once. Access tab montage from the View►Screen menu, or through the keyboard shortcut: command + M (Mac) or control + M (PC/Linux).
