Is it possible to read parameters from an external file into xosc?

[fernandoGitHub]

Currently I'm using ParametersDeclaration for defining the global variables in the xosc. As I want to prepare several permutations of this scenario with different values, I will end up with 20 files looking exactly the same beside the ParametersDeclarations section. For example:

` <ParameterDeclarations> <ParameterDeclaration name="Catalog_Vehicles" parameterType="string" value="../resources/Catalogs/Vehicles"/>

	<!-- Vehicle Types -->
	<ParameterDeclaration name="EgoVehicle"       parameterType="string" value="Police_Car"/>
	<ParameterDeclaration name="Lead_0"           parameterType="string" value="Tesla_3_White"/>
	
	<!-- Initial Speeds -->
	<ParameterDeclaration name="Ego_V0"           parameterType="double" value="35.0"/>
	<ParameterDeclaration name="Lead_0_V0" 	      parameterType="double" value="10.0"/>
	
	<!-- Breaking Parameters -->
	<ParameterDeclaration name="Ego_Deacc"        parameterType="double" value="-8.0"/>
	<ParameterDeclaration name="delta_V"          parameterType="double" value="${$Ego_V0-$Lead_0_V0}"/> 	
</ParameterDeclarations>`

Is there a way to create a file of use cases (or permutations) where each permutation will be defined more or less as:

<Permutation name="P1"> <ParameterDeclaration name="EgoVehicle" parameterType="string" value="Police_Car"/> <ParameterDeclaration name="Lead_0_V0" parameterType="double" value="10.0"/> </Permutation>

So, in my final xosc, I can load the permutation (similar to a Catalog) and use its variables. More or less like:

<ParameterDeclarations> <ParameterDeclaration name="EgoVehicle" parameterType="string" value=<CatalogReference catalogName="VehicleCatalog" entryName="$CarVehicle"/>/> </ParameterDeclarations>

Something like that. Sorry for destroying the structure of the xosc in the example above :-)

Yes it should be possible, by using deterministic parameter value distributions.

See OpenSCENARIO User guide 9.3. Parameter value distribution file for introduction.

See esmini User guide - Parameter distributions for info on how to apply in esmini.

Here's a parameter value file example: cut-in_parameter_set.xosc

Let us know whether this is applicable for your use case or not.

Thanks a lot Emil!

It is working perfectly!
