Hi,

MG5aMC assumes that all model defines alpha_s in the model.
This typically means that you need to define a parameter "G" and "aS" in your model.
even if you do not care about strong interactions. (This is important for the running)

If you do not need those for your model then you can put arbirary value for those.

Cheers,

Olivier
