GUI

The first steps of the workflow are accomplished through the GUI.

Invoke the GUI

After the library has been installed, you can invoke the GUI from either the Tools ribbon or the command window.

Figure 1. romAI Director in Tools Menu

To invoke the GUI from the command window, type the command romAIdirector. The GUI is shown as in the following image.

Figure 2. romAI Director Window

The GUI has the following sections:

File Menu contains generic file read/write options and generic utility actions.
Figure 3. romAI Director File Menu
Ribbon contains buttons to invoke actions that are applicable to the selected tabs.

Tabs provide a switching mechanism between Pre-Processor, Builder, and Post-Processor functionalities.
Selection Tables provide options to select signals/models. In the case of Pre-Processor, there are utilities present on the top of the table. These utilities are applicable to table only.

Plot Canvas shows 2D/3D plots.

File name info shows the name of the files/folders in use.

Note the following commands and operations:

clear all: This command makes the romAI GUI unusable.
close all: This command closes the romAI GUI, in addition to other close commands, according to Compose OML logic.
GUI instances: Use one GUI instance at a time. For example, you cannot open two romAI GUIs at the same time in the same instance of Compose.
