Interacting with Server

To make the interaction with the server easier we provided a minimal API and one can run scenarios from Matlab. Doing something similar in R is also straightforward and will be implemented in the future.

Matlab

The required Matlab functions are available as part of the gwtools repository.

The first step is to launch the server. To do so under a powershell execute the following

MantisServer.exe -c .\mantisConfig.ini 

wait a minute and when you see the message Mantis Server Ready... you can proceed to the next phase

In the Matlab workspace set up the path to the Mantis client executable

client_prog = 'path\to\MantisClient.exe';

Obtain a list of all scenario options

scenario = MantisInputs();

Scenario is a struct with multiple options. The options infile and outfile are the names of the files where the input and output data will be written. The output file will be deleted every time the Mantis runs.

Let's set up a scenario

scenario.Regions = {'Subregion10','Subregion11'};
scenario.loadScen = 'SWAT1';
scenario.Crops = [-9 0.5];

Then we can simulate the scenario using

[btc, tf] = runMantis(scenario, client_prog);

Calculate and plot the percentiles

tmp = prctile(btc,[10:10:90]);
plot(tmp')

To quit the server run the following

runMantis([], client_prog, 'quit');
