[gmx-users] how many pairs are exchanged in replica exchange

[sarbani chattopadhyay]

Hi,
   I am new to Replica exchange molecular dynamics. 
    I obtained the optimal temperature distribution based on the lowest and highest 
tempearture and exchange probability from the REMD caclulator , available through the 
gromacs homepage.
There were 17 temperaure values as output. I prepared 17  ".tpr" files based on the 
temperatures.
What I want to know is that at each attempted step of replica exchange, how many pairs of 
replicas will be exchanged, and how this is decided?

Thanks in advance,
Sarbani
