[replica] section
-------------------------------

Specify the parameters of the replica exchange Monte Carlo part, such as the number of replicas, the temperature range, and the number of Monte Carlo steps.
The example is shown as follows.

  ::
  
        [replica]
        nreplicas = 3
        nprocs_per_replica = 1
        kTstart = 500.0
        kTend = 1500.0
        nsteps = 5
        RXtrial_frequency = 2
        sample_frequency = 1
        print_frequency = 1

Input Format
^^^^^^^^^^^^
Specify a keyword and its value in the form ``keyword = value``.
Comments can also be entered by adding # (Subsequent characters are ignored).
