The data list is broken down according to a hierarchical organization. A "+" sign next to each category or subcategory in a list indicates that there are other items contained within the category or subcategory.

• Click the "+" sign to expand the list to show all of the subcategories (e.g., neuron components are listed under the Neurons heading)
• Continue expanding the list by clicking on "+" signs; when no more "+" signs is displayed, each individual object is listed separately.
• To select an object (or group of objects), click the name of the object; clicking a heading selects all objects under that heading.
• To collapse the list, click the "-" sign next to a set of objects.

If you are viewing a tracing composed of several sections, or a single section containing contours within other contours, use Select Objects in 3D Contours.

To select objects in 3D contour:

1. Select a single contour.
2. Right-click, and select Select Objects in 3D Contours.
   All contours of the same type throughout the 3D structure are selected; if these contours contain other objects within them, those objects are also selected.

 

Neurolucida Explorer is unique in that you can choose how you would like to show that given objects are selected. There are two graphical cues to indicate when an object is selected:

• Display Selection Cubes button. When clicked, a red cube surrounds the selected objects.
• Display Selection Squares button. When clicked, white squares appear on the vertices of selected curves or selected markers.

You can use both buttons together to indicate selected objects.
