Downloadable Scenarios

Download the project and import it into STEM using File->Import...->Existing projects into workspace
 Please Read-me first  Installation Instructions
 Documentation  To Learn more about the downloadable scenarios please see the tutorials on the STEM wiki
 (new) Importing Shape Files  This single archive contains an example of how to import and create a STEM graph from a shape file (.shp) in your workspace. If uses STEM's pajek graph generator.
 Ebola Models  This single archive contains three different projects with several Ebola scenarios. Requires the latest STEM Integration build on or after Sept 26, 2014.
 Ebola Zoonotic (Re)Introduction  This archive contains a new model generator example extending the Ebola Model to support re-introduction from Zoonotic Reservoir, and a simple project demonstrating that model. See the readme.txt within the Archive !
 Dengue Examples  This archive contains three different projects with several dengue fever models and scenarios. Requires any STEM build on or after April 2, 2014.
 Model Generation Sample Scenario  This is the bare bone demonstration scenario used in the model generation tutorial video ( The scenario requires 2010 Earth Science data.
 Avian Influenza  As an example of a stochastic model (new in STEM 2.0), this shows a hypothetical outbreak of an avian influenza (e.g. H7N9) in China spreading from birds to a few hundred people over a period of one year. It also demonstrates the effect of a mutated virus transmitting human-to-human. Requres a STEM build on or after 8/21/13.
 Salmonella  In this example the spread of Salmonella from farm to fork is demonstrated for the production and consumption of pork in Germany based on findings from the scientific literature.
 Migratory Birds  This square lattice scenario provides an example of output from the Seasonal Migration Edge Graph generator, and it's use with a Seasonal Migratory Population Model to create a model if migratory birds
 Population data replay demo  In this demo, we read mosquito population data from the external file system and use it to drive a model of Malaria in Thailand
 Food borne disease Model  This first demo mode of foodborne disease models beef production from cattle. The food production graph, created with pajek, is inserted into Argentina in this example scenario.
 ScenarioTutorial  Project containing templates to use with the new tutorial on how to build food borne disease scenarios.
 Evacuation demo  The evacuation demonstration project aims to demonstrate how interventions can be used in STEM to control an outbreak.
 Chickenpox !!  The ChickenPox example scenario shows how to use the new aging (demographic) population model. The initial conditions in this example start the population far from equilibrium.
 Asia Mosquito Density Model  Demonstrates how the earth science data can be used to generate seasonal mosquito density estimates in Asia. Requires installation of the optional 2010 Earth Science Data Feature from the STEM update site and the Global Geography and Global Earth Science models (below).
 Automated Experiment Example  Demonstrates the automated experiment feature in STEM and how it is used to fit unknown EPI parameters to a reference incidence data set
 Global Earth Science Models for release 1.2.1 and later  Continent-level models of Earth Science Data including elevation, rainfall, temperature, and vegetation coverage. OBSERVE: You need to access the STEM update site and install the "STEM Earth Science Data for 2010" plugin to use these models.
 Multi-Population Example  Demonstrates a simplified multi-population disease model with anopheles mosquitos and humans
 Pajek Import Example  Demonstrates a simplified multi-population disease model where the entire graph is created using the new Pajek Import facility
 Square Lattice Example  Demonstrates both population migration and disease spread on a Square Lattice
 Mexico USA pandemic flu scenario  An example H1N1 Simulation
 Global Geographic Models  Contains generic model building blocks organized by Continent. Geography, transportation, and People (no disease models).
 Super-Continent Examples  Contains Demo Models using Continent Definitions included in Global Geographic Models Package above (required). See Readme.txt
