An analysis project brings your model, simulation, analysis, and desired output together in one place. The resulting file is saved as a LEGION Analysis Project file (*.ana).

To create a new analysis project:

1. Click or select File > New.
   • The New Project Files dialog is displayed.
     
2. Click the browse button to the right of the Data Source box and select the appropriate LEGION Simulator File (*.ora) or LEGION Simulation Results (*.res) file by navigating within the 'Open' dialog.
   • You can also type in the file path. If the file does not exist, or there are other problems with the file, the outline of the Data Source box glows red, and a tooltip describes the error:
     
3. The Project Type is selected automatically, based on the Data Source. It will either be Simulation or Results.
   • Changing the Project Type is a quick and easy way to switch the selected Data Source between a LEGION Simulator file and a LEGION Simulation Results file.
     Note: Both files must exist in the same folder and have the same filename.
4. The Project Base Folder is automatically identified from the selected Data Source.
   • This is the folder containing the Data Source and serves as a reference folder for using relative paths with other analysis input and output.
     Tip: Using relative paths in your project allows you to move the project, and its input and output, to a different folder, a different drive, or even a different PC, without needing to manually update all file paths e.g., Timeline track filenames, Generalised Journey Time outputs.
5. The Model File is automatically identified based on the Data Source file, but for this to work both files must be in the same folder.
   • To manually identify the Model File (*.lgm), or choose a different one, click the browse button to the right of the Model File box and select the appropriate LEGION Model File by navigating within the 'Open' dialog.
     Tip: If the Model File is in the Project Base Folder, the path is automatically converted to a relative path.
   • You can also type in the file path. If the file does not exist, or there are other problems with the file, the outline of the Model File box glows red, and a tooltip describes the error.
6. LEGION Simulator will attempt to identify all Scenario files for the selected Model File. If any are detected, they are listed in the Scenario drop-down.
   Note: It can take a few seconds to identify the Scenarios in a Model File.
   • Use the Scenario drop-down to quickly select the Data Source for the named Scenario, without needing to browse for it.
   • LEGION Simulator tries to match the selected Data Source to an identified Scenario. If a match is found, the Scenario is automatically selected in the Scenario drop-down.
     • To match, the Data Source must start with the Model File name, then an underscore, then the Scenario name.
     • Scenario files that don’t follow this filename pattern will not be detected automatically.
   • If a match cannot be found, the Scenario drop-down remains blank.
   • If a Model File does not contain Scenarios, the Scenario drop-down is disabled.
7. If your simulation includes Aimsun vehicles, check the box labelled Load Aimsun simulation result file, click the related browse button to the right of the box and select the appropriate 'xml' file.
   Tip: If the Aimsun Result File is in the Project Base Folder, the path is automatically converted to a relative path.
   • You can also type in the file path. If the file does not exist, or there are other problems with the file, the outline of the Aimsun Simulation Result box glows red, and a tooltip describes the error.
   • See Showing vehicles in LEGION Simulator for more information.
8. When you have selected your project files, click OK.
   • The model is displayed in the analysis workspace.
9. Click or select File > Save and choose a name and location for your LEGION Simulation Analysis File.

You are now ready to start your analysis session.
