it _really_ depends on what you're trying to study for your
system. It isn't clear what you're trying to do. The time of the
simulation also depends on what you're trying to do and the system
properties. If you're trying to optimize structure, it can help to
try several annealing protocols and see if the results are sensitive.
With LES, you can look to see if the copies converge at the end of the
annealing, or if they anneal to different conformations.

dear amber users
I use the LES method for the protein (haloalkane dehalogenase about 300 aa) with small substrate(trichloropropane), but I dont have many experiences with LES running. I use these temperature parameters for
heatin phase:
&wt type='TEMP0', istep1=0, istep2=2500, value1=298.16,
value2=400.0,
&end
&wt type='TEMP0', istep1=2500, istep2=52500, value1=400.0,
value2=400.0
and these for cooling phase:
&wt type='TEMP0', istep1=0, istep2=80000, value1=400.,
value2=0.0
So, I would like to know if these temperature parameters are optimal for such system.
best regards
Petr
