Positional restraints are applied to the heavy atoms of the peptide. In the RESPA scheme, the PME calculation is performed every 2 steps and the thermostat and barostat momentum are updated every 10 steps.

In this scheme, the system is weakly coupled to a heat bath with some temperature. The thermostat suppresses fluctuations of the kinetic energy of the system and therefore cannot produce trajectories consistent with the canonical ensemble. The temperature of the system is corrected such that the deviation exponentially decays with some time constant .
