    Persefone.jl Desktop

    Persefone.jl splash screen

    This is the graphical user interface to the Persefone model. With it, you can watch a simulation run unfold and interactively explore how the model functions.

    Install & run

    To install: Install Julia and download/clone this repository. Open a Julia REPL in the downloaded folder and execute the following to install all dependencies:

    using Pkg
Pkg.activate(".")
Pkg.instantiate()

    To run: Run desktop.jl. Alternatively, open a Julia REPL in this folder and run:

    using Pkg
Pkg.activate(".")
using PersefoneDesktop
launch()

    Note: Due to the necessary pre-compilation done by Julia, installing and launching the application can take quite a long time. (Start-up time with desktop.jl is currently about 2 minutes.) We will reduce this as much as possible in future releases.

    User interface

    Persefone.jl Desktop screenshot

    The main window component is the map view. This displays a land cover map of the simulated region: dark green are forests, light green grassland, yellow fields, red built-up areas and blue water. On it, little circles show the position of individual animals, with different species denoted by different colours.

    Below the map is the control bar, with the following elements (from left to right):

    • Back button: Rewind the simulation by one day.

    • Step button: Advance the simulation by one day.

    • Run button: Run the simulation until the button is pressed again or the end date is reached.

    • Progress bar: Shows the percentage of time elapsed between the start and end dates of the simulation.

    • Speed slider: Set the time delay between each simulation step when running.

    • Date: Shows the simulation date currently displayed on the map.

    Above the map is the menu bar, with the following options:

    Simulation:

    • New simulation: Reset the model and start over.

    • Configure simulation: Change the model settings (not yet implemented).

    • Load saved state: Load a model object file saved by a previous simulation run.

    • Save current state: Save a model object file for later use.

    • Quit: Close the application.

    Data:

    • Show population graph: Show a window with a graph of population sizes over time in the current model run.

    • Save simulation output: Save the model output data to file (saves both raw CSV data and generated graphics).

    Help:

    • Website: Open the main Persefone.jl website in a browser.

    • About: Show a window with core information about the application.
