Hi,
I want to calculate the PMF of two amino acids in my protein. I suppose "Free Energy of Conformation Change" method should be used.
I guess dU corresponds to the total energy of the system. Am I right? I want to use just the interaction energy between those two amino acids to calculate PMF. Is there any way to control what energy PMF uses (like PairInteractions', etc.) ?
Is there any reference for "Free Energy of Conformation Change" method used in NAMD ?
best
Arturas
P.S. Below my script:
freeEnergy on
freeEnergyConfig {
urestraint {
dist pmf (A,85,CA) (A,117,CA) kf=50, low=7.0, high=14.0
}
pmf {
task = grow
time = 10 ps
print = 1 ps
}
pmf {
task = up
time = 500 ps
}
pmf {
task = stop
time = 10 ps
}
pmf {
task = down
time = 500 ps
}
}
