As we saw before, graphs enable to represent structured data with nodes and associated attributes. Graphs also have global attributes defining characteristics shared by all nodes, as for example voxels size. Nodes also can be linked by relations. This is used in sulci graphs to represent several units extracted from a sulcus. You can see these relations by selecting the neighbours of a node.
The main attributes in graph nodes (for sulci and ROI graphs) are name and label. These 2 attributes have the same role : naming a node. Then, it is possible to make a link with a nomenclature file in order to associate a color to each value of attributes name or label.
So, what's the use having 2 different attributes with the same role ? In some case, we need a double identification. For example, in a automatic sulci recognition, nodes are renamed by computer experts. When consulting the results, you might want to rename a sulcus and keep the original identification, which is highly recommended.
Follow these steps :
Put the graph in a 3D window. The nodes are not visible yet. Indeed, for big graph, it is more convenient to see only chosen nodes rather than all nodes.
Right click on the window and select the menu View / select objects. A browser window opens.
Then, you can select the nodes you want to see by clicking on it in the browser window.
When a node is selected in the browser window, it becomes visible as an object in the 3D window.
If you want to see all the nodes of a graph, you can use the object menu Display -> Display nodes available by right clicking on the graph. Selects a window and use this feature, the graph will be loaded in the window and its nodes become visible. If there is no opened window, Anatomist will open a new 3D window and load the graph in it. If there are several windows and none is selected, Anatomist will load the graph in each window.
