Issues in StateDataReporter

[argha-chakraborty]

I am running the exact same code given for the alanine dipeptide case. The following error is coming -

#"Step","T[atoms] (K)","T[s_phi] (K)","T[s_psi] (K)","s_phi","phi","s_psi","psi","Speed (ns/day)"
Traceback (most recent call last):

openmm.OpenMMException: Invoked getKineticEnergy() on a State which does not contain energies.

When I am calling simulation, reporters.append(app.StateDataReporter()), no error is shown. But for that case 'multipleTemperatures=True' is not available.
