Ebola How To

Under construction How to install and run the Ebola Models

You can download the ebola models here.

This archive contains multiple projects and multiple scenarios for Ebola. The archive also contains the Ebola model itself which can be opened and edited with the STEM model generator. For more information on the model itself please see the page Ebola Models.

To install the models:

1. Install the latest weekly integration build of STEM.

2. In the event we later release new versions of the Ebola models that depend on climate factors around the globe. We suggest you also install the global data on climate and environmental factors.

3. Download the Ebola Models as a single archive.

4. Extract the Archive so all the project folders it contains are in one single place.

5. Navigate to your STEM installation folder. Then navigate to the folder workspace

6. Move or copy all the project folders from step 4 into the folder workspace.

7. Launch STEM. Just click on the STEM icon in your install folder. After STEM launches

• close the welcome page

• switch to the Designer perspective (the tab at the top).

8. From the menu bar select >File>import

9. Select >General>Existing Projects into Workspace. Click Next.

10.Click Browse. Then navigate to your STEM Workspace folder if it does not already appear.

11. Click Open

12. You should see 6 separate Ebola related project folders, all selected, as shown in the image below. Click Finish.

13. After the import completes the Designer perspective of your workspace should look something like this

14. The project folders you see include:

• EbolaAfrica (all of Africa Admin Level 2)
• EbolaInWestAF3 (3 countries in: Wst Africa, GIN, LBR, SLE. This is Level 0, a very simple 3 patch model but one that can be used to fit model parameters to data emerging for those three countries)
• EbolaInWestAF3LVL2 (Same as above but at Admin Level 2)
• GlobalEbola (The whole world. See the instructions on running the Global Ebola Model to learn how to change your memory settings to run this.
• GlobalGeography (reference data required to run the global model above)
• org.eclipse.stem.ebola (The model itself. See the page the STEM Model Creator to see how to view and edit the model and to view the generated source code inside)

15. Open the EbolaAfrica project folder.

16. Open the scenarios folder

17. Select the "Deterministic" scenario, right click, and select "Run"

18. STEM will switch to the Simulation Perspective as Shown below.

19. UI Tips

• To move the map click and drag
• To zoom use up and down arrows
• Double click on any map region to open a timeseries view (line chart) for that region
• Right click on a blank part of the map. Select Gain Factor. Set it to 1,000,000

20. Simulation Controls

• One menu bar select >Window>Preferences
• Expand STEM
• Select Simulation Management
• Set "Milliseconds to Pause Each Cycle" to zero if you want to run as fast as possible (slow it down for small scenarios if you want to see the spread on the map).
• There are many more pages on this wiki about how to use loggers, model interventions, etc. Please read the doc.
