VND Features
VND provides a range of features to assist the viewing and exploration of a model neuronal system and simulation results.
This page contains a gallery of images which exemplify some of these features.

Per-representation neuron counts. When search queries are used to create graphical representations, the number of neurons in each representation is displayed.

Compartment time series animation GUI. Two example time frames are shown, along with the color scale in use.

Hierarchical tree view of model. The organization of the loaded model is displayed: files, populations, and groups. All elements of the tree view are expandable/collapsible, and are clickable to directly help construct search queries.

Bar scale, side ruler, and grid overlays. For illustration here, the center of the grid overlay is magnified to show the fine grid lines. When a user is zooming around a large model system, the overlays dynamically change, providing a continuous sense of relative size from a complete system down to details of individual cells.

Cell morphology scaling. All cell morphology drawing styles can be scaled by diameter, with essential features, branching, and relative widths preserved. Individual neurons can be seen when zooming out to display larger model systems. Combined with scalable display of soma spheres, multiple elements and regions of models can be highlighted.

Compartment-type cell coloring. Coloring cells by their compartment type (left panel) is compared to coloring cells by their cell type (right panel). In the left panel, axons are shown in green, basal dendrites in red, apical dendrites in blue, and cell somas in silver. Combined with selection and highlighting of individual cells and cell populations, the coloring method can be used to explore distribution and proximity of cell morphology compartments across a model neuronal system. Compartment-type coloring can be applied to all VND morphology drawing styles (line, draft morphology, and full-quality morphology).
