Dear gmx-users,
(This is not related to my previous question about the failure of the
simulation. Now I guess that there are some technical problems in our
cluster system.)
Hello gmx-users, I am not a quite new user, but still don't know many
many thing.
Planning an experiment I hope to listen to your advices.
Recently I plan to perform free energy calculation to test the stability
of a loop in a protein.
To do so, I will select two atoms; one in the backbone atom of the loop
and the other in the backbone of the protein nearby the loop region.
Then, those sites are connected by a [ bond ] and the spring constant
will be changed from 0 to 100 as lambda changes from 0 to 1. (The
equilibrium length is fixed to 20 A.)
I am wandering whether this simulation will be generally accepted or not.
How does such a calculation reveal the "stability of [the] loop"? You
need a more precise goal in order to design a calculation to measure
something. Perhaps some more background reading is in order :-)
