The Primary Toolbar

At the top of the Main Window, below the Menu bar, you should find the primary toolbar:

Each of those buttons corresponds to an action:

1. Add Canvas -> Adds one more canvas:

2. Create Manual Link -> Will allow you to manually connect two nodes together with an arrow indicating their connection. After selecting this option, click on two nodes, one after the other, to create a link between them. The first node selected will be the parent node, and the second the child. Click the button again to cancel the operation. A dialog box will appear after creating the link to prompt for more information about the connection.

3. Upload Selected Files -> After selecting at least one entity in the canvas with an Entity Type that belongs in the Materials category, you can use this option to upload the file it represents to the server you are connected to. If not connected to a server, this option does nothing.

4. Select Leaf Nodes -> This option will select all the Nodes that have 1 or more incoming links but no outgoing:

5. Select Root Nodes -> This option will select all the Nodes that have 1 or more outgoing links but no incoming:

6. Select Isolated Nodes -> This option will select all the Nodes that have no outgoing nor incoming links:

7. Select Non Isolated Nodes -> This option will select Nodes that have at least 1 incoming or outgoing link:

8. Find Shortest Path -> After selecting exactly two nodes, if there is at least one path between them, this will find the shortest path from one of the nodes to the other:

9. Merge Entities -> In order to simplify your investigation you could merge two or more entities together. A dialog will pop up where you will have to select which entity will be the primary entity. By clicking merge all the entities will be merged to the primary entity. All their properties will become the primary entity's properties, and all their links will point to and from the primary entity. If the same property name exists in multiple entities that are to be merged, subsequent property values after the first one are ignored. The only exception is if the property has no value (i.e. the value is 'None').

10. Split Entities -> This can split one entity to multiple ones. You can pick which entity will keep which links. Useful in cases where you discover that a single node actually represents two distinct entities, and some links point to one and others to the other.

11. Generate Report -> This will pop up a wizard dialog, guiding you through the process of automatically generating a PDF report for all the selected Entities.

12. Rearrange Graph -> Once clicked, the nodes in the canvas will automatically and deterministically be rearranged to a configuration that tries to minimize overlaps.
