Menu Items
The appearance of the STEM user interface (UI) will be a little bit different depending on your operating system (e.g. Windows or Mac). When you first launch stem you will probably see a welcome screen. Closing that, you will see the STEM UI. Figure 1 shows the UI as it appears for STEM V2.0 running on mac. The first thing you will probably notice are a large number of colorful shortcut icons across the top near the menu bar.
Figure 1: The STEM UI. The UI appearance will differ slightly between operating systems (e.g. Windows or Mac).
Notice the many shortcut icons along the top near the menu bar..
To understand what the shortcuts actually do, you can mouse over the icons, or simply go the menu bar and click >NEW you will get a drop-down list that shows all the available shortcut icons again along with a description.
Figure 2: Select >NEW on the menu bar. The same shortcut icons and their meaning are also visible on the NEW menu..
What do the shortcuts do ?
The shortcuts help you create new objects in STEM that, when assembled together allow a user to define and run a scenario or experiment. The list below shows a list of these objects in roughly the order you will want to learn to use them. In the list below the descriptions are also links to the right documentation page describing their use.
- STEM Project This creates a STEM Project Folder. Your workspace can contain many folder as shown in the Project Explorer (see Figure 1).
- Scenario Create a Scenario. Scenarios are a collection of objects that taken together can actually run. You can have more than one scenario in a Project.
- Solver Create a Solver. All Scenarios need one to run. Solvers integrate your models over time.
- Model Create a new Model. Models get added to scenarios.
- Sequencer Create a Sequencer. This defines time for your scenario (and is added to it).
- Population Model Create a Population Model. What's a disease without a population to infect?
- Population Initializer Create a Population Initializer to set the initial state of a population.
- Disease Model Create a new Disease Model
- Infector/Inoculator Creates an infector/innoculator/or initializer for a disease model.
- Logger Create a logger object. Lots of possible loggers can be added to your scenario including delimited files, video, etc.
- more advanced functions and features
- Graph Create a custom graph. This might be a farm or a square lattice.
- Automated Experiment An advanced tool to automatically optimize or fit parameters in a scenario.
- Experiment Run Experiment (like a set of scenarios) in batch mode.
- Triggering Interventions
Figure 3: The Tools Menu. Begining with STEM V2.0 users can access a set of tools. The first tool can be used to update projects created in STEM V1.x or earlier so they run will all features of STEM V2.0.
