I'm trying to set the variant subsystem of a simulink model from matlab, by the set_param function.

The model has some already done subsystems and I added 2 new subsystems (test1 and test2); If I set one of the already done subsystems it works, but if I try to set one of the new variant subsystems it doesn't works.

I called the new subsystems test1 and test2, also in the variant choice table of the block parameter.

If I use this command it works:

set_param(['sm_car' '/World'],'popup_scene','Road Two Lane');

but with this command it doesn't works:

>> set_param(['sm_car' '/World'],'popup_scene','test1');

The error is:

Invalid setting in Environment block (mask) 'World' for parameter 'popup_scene'

Caused by:

Option specified is not valid.

Why?

It looks like you have a mask on a subsystem and are using that mask to control the variant choice. You need to associate that mask variable with the variant selection. This link shows a couple of different ways to do this. The first example looks like what you need.
