[gmx-users] Fw: minimization for final configuration

[Mahboobeh Eslami]

dear Justin thanks for your replyThe plot of the RMSD against time for the trajectory generated with g_rms shows a maximum RMSD about 0.195 nm.
I set cut-off value to 0.2 nm for g_clusters command.
Is it a appropriate value?Sincerely.On Tuesday, September 30, 2014 2:17 PM, Justin Lemkul <jalemkul at vt.edu> wrote:

An average structure might be totally unphysical.  Energy minimization of an 
unphysical structure leads you to something that is probably useless.  I'd 
suggest doing clustering if you're interested in the predominant conformation(s) 
during a certain time period of the simulation.
