I want to run it in a headless mode i.e no GUI. I want to be able to invoke
in batch mode ( ie headless standalone) a model developed via graphical
modelling tool of qgis.
So, ideally i dont want to connect to x-server
this is needed for automation purpose.
Cant really use pytho

thanks Matthias,
Actually this is what i am trying to do.
i need to calculate wetness index, so i have developed a model in qgis
graphical modeler that invokes grss-saga algorithsm to calculate slope,
wetness index etc.
all i want to do is to run that algorithm in a headless mode.
So, using pr
I have never run a processing model standalone, so I cannot help there.
I don't know how closely tied this is to GUI related things. It may or
