Hi
But your previous mdin had ntt=1, which means it would never use the 
gamma_ln parameters.
You need to read a bit on what that parameter means.
There is a recent paper by Alexey Onufriev on how conformation the speed 
of sampling depends on the value you choose.
Biophysical Journal 108, 1153-64 (2015)
Bottomline, if you are simulating equilibria (as opposed to caring about 
the actual time scale of things), then it does not matter which value 
you use, you will get the same answer. However, a smaller value will 
sample the same space 'faster'. For a very small system, if you use a 
small value of gamma_ln, you run the risk of having large temperature 
fluctuations, which can mess things up.
If you care about the actual time scale of processes, many of us have 
found that a value of ~50 seems to match the time scales as if you were 
running inexplicit solvent.
