The Metaparameter explorer (Metaparameter Explorer) can be used to attach global expressions directly to model variables for situations where the expression editor Function Editor has not been enabled by default.
...
By default, all recorded items are returned, as configured from within the Source application (Running scenarios). Alternatively, you can specify specific items to record by using a command line argument:
...
Several global expressions can be set using the -v argument:
Set the values:
Code Block RiverSystem.CommandLine -m Client -v "$metaParam=2.5"
- Set multiple expressions:
...
The next example runs the project from start to finish and puts all recorded values in the file ‘test.csv’.

PEST calibration using the command line
PEST (Parameter ESTimation and uncertainty analysis) allows analysis of complex environmental models, and can be used in Source for calibration of catchments. You can use the command line to do calibration and uncertainty in a catchments model. The steps to do the calibration are as follows:
- Starting with a Source Catchment project file, use the new calibration tool to set up ‘global expressions’ for the parameters of the rainfall runoff models. When defining the metaparameters in the Calibration Wizard (Figure 168), the list of Existing Metaparameters will be used in the parameter file for invoking riversystem.commandline;
- Turn on any recorders for the hydrological quantities that will be used in the objective function. In step 4 of the Calibration Wizard, choose Manual optimisation and enable Create global expressions for use from an external tool;
- Save the project;
- Set up the Riversystem.Commandline input file;
- Setup the PEST input and template files;
- Prepare a batch file to invoke the commandline and pre-processors; and
- Run PEST.
Once the Calibration wizard has been set up, start the command line server (riversystem.commandline -p projectname.rsproj -m server) and then PEST (pest pestcontrolfile.pst).
