Thermodynamic and Sampler States

The module openmmtools.states contains classes to maintain a consistent state of the simulation.

• ThermodynamicState: Represent and manipulate the thermodynamic state of OpenMM System and Context objects.
• SamplerState: Represent and cache the state of the simulation that changes when the System is integrated.
• CompoundThermodynamicState: Extend the ThermodynamicState to handle parameters other than temperature and pressure through the implementations of the IComposableState abstract class.
• GlobalParameterState: An implementation of IComposableState specialized to control OpenMM forces’ global parameters.

States

ThermodynamicState	Thermodynamic state of a system.
SamplerState	State carrying the configurational properties of a system.
CompoundThermodynamicState	Thermodynamic state composed by multiple states.
IComposableState	A state composable through CompoundThermodynamicState.
GlobalParameterState	A composable state controlling one or more OpenMM Force’s global parameters.
