Dear Elisabeth,
Try this:
First import the MMTKinter
from MMMD.MMTKinter improt MMTKinter
Now let's initialize the class:
energy = MMTKinter(chimera.openModels.list(id=0), nogui = True)
Now let's create the universe:
energy.loadMMTKCoordinates()
And now let's print the energy
energy.universe.energy()
I think if you do this from the IDLE you should get the energy. You have to take into account that in id = X, X is the model number for what you wish to calculate the energy when you initialize the function.
Kind Regards,
