Hello, I am trying to do REMD for a protein unfolding. I am following the information given in http://wiki.gromacs.org/index.php/REMD but I am completely new in these type of simulations. I would like to ask two questions to more advanced users. I hope you could help me: -I have seen that the exchange rate should be typically between 0.2 and 0.3. Where can I extract the exchange rate from my outputs? For example in the output below the exchange rate would be "Repl pr .08 .00 .13"? Should I calculate a mean for all exchanges and all replicas and check if this mean is between 0.2 and 0.3?Repl 0 <-> 1 dE = 2.492e+00Repl ex 0 1 2 3 4 5Repl pr .08 .00 .13Replica exchange at step 2000 time 4Repl ex 0 1 2 3 x 4 5Repl pr .00 1.0 -Another question is about restarting simulations. I have though doing it with tpbconv and then concatenate the .log files to use demux.pl. Is this correct? Thank you very much for your help.
