Note: Some features of GATSE (eg, sophisticated constraints) require version 10.0.8.32bit of ATSV.

Configure the GTSE Plugin.
1. Open Eclipse's preferences (Window, Preferences on Linux/Windows, or OSATE2, Preferences on Mac OS X).
2. Expand the OSATE Preferences item in the list on the left.
3. Click on ATSV Integration.
4. Each option can be left at its default, but the Directory for ATSV Files can be set to a more easily-accessed directory if need be.
5. Click OK.
6. If you made any changes, restart OSATE.
Create, or import, an GTSE-compatible project.
- Example projects are available in the GTSE-Examples directory of this repository.
If you've imported a project, open the associated .config file.
Saving .config files triggers the generation of pre-requisite files -- so add a newline, space, or comment and save the file.
[Optional] Verify that the following files have been created in the directory you specified as part of step 1.4:
- ATSVConfig.ecf
- connector.jar
- input.xml
- output.xml
- parser.jar
- request.properties
- run.sh (Linux and Mac) or run.bat (Windows)
- runATSV.bat (Windows only)

Launch OSATE.
Open the project containing the GTSE-compatible packages.
[Optional] Test the generated setup.
1. Note the contents of output.xml.
2. [Optional] Modify the contents of input.xml.
3. Note the contents of input.xml.
4. Run a single execution of the GTSE plugin by executing run.sh on Linux / Mac OS or run.bat on Windows.
Launch ATSV according to the instructions:
- Windows:
  1. Copy the runATSV.bat file generated previously to the ATSV directory.
  2. When prompted, replace the original runATSV.bat.
  3. Double click runATSV.bat.
- Mac OS and linux: Double click ATSV.jar in ATSV's dist folder.
Load the generated engine configuration file into ATSV.
1. Click File.
2. Click Link to Exploration Engine.
3. Verify Link to existing engine configuration is selected.
4. Click OK.
5. Navigate to and select the ATSVConfig.ecf file generated previously.
  - This file will be in the directory you set in the ATSV Integration preferences in OSATE.
6. Click Open.
In the window titled Engine Frame: CommandLineProblem, click Start.
Wait for the runs to complete. Depending on model size, analyses selected, and number of runs, this may take a while.
In the window titled Trade Space Visualizer, click Plots.
Select the type of plot you would like to view.
- Note that only Windows users will be able to view 3D plots.
