Using a nomenclature file (icon : ) offers another way to browse a graph. For example, you load 2 labelled sulci graphs and the nomenclature of sulci recognition. Then you can select a sulcus by choosing its name in the nomenclature. So the choosen sulcus is displayed in each graph window.
Using a nomenclature also enables to associate a color to a label and/or a name. Thus you can standardize the display of graphs. A specific label or name will be displayed with the same color in every graph.
A nomenclature file has the .hie extension and is a simple text file. et sont de simples fichiers texte.
Handle a nomenclature :
Put the nomenclature in a browser window.
You can now select nodes in graphs by clicking on the nomenclature's nodes. It is organized hierarchically. This means that you can select all the graph nodes that are under a nomenclature name by clicking on this name. For example, if you click on the name of a lobe, all sulci in this lobe become selected. And when you click on "brain" in a sulci nomenclature, all identified sulci become selected (but not thosewith the label "unknown"). It makes it easy to visualize and select things by region.
NB : Simple nomenclature files for ROIs can be created using Nomenclature => Personal menu in the ROIs module in Anatomist.
NB : The nomenclature must match the graph type : value of "graph_syntax" attribute in the nomenclature must match "Value" colon displayed for the graph in a browser window (eg : "CorticalFoldArg" for a sulci graph).
