Dear all,
I have done the constant pH MD of Amber for 1ns. The result is good. Then I try to run for 50ns, which restarts from the coordinates and velocities of the 1ns. But I the energy changes very much, and the structure is unstable. Following is the .in file of mine:
&cntrl
imin=0, irest=1, ntx=7, ntb=0,
igb=2, saltcon=0.1, ntpr=1000, ntwx=1000,
ntt=1, tautp=2.0,
tempi=300.0, temp0=300.0,
scee=1.2, nrespa=1,
ntc=2, ntf=2, tol=0.000001,
nstlim=2500000, dt=0.002,
cut=30.0,
icnstph=1, solvph=7.0, ntcnstph=3
/
I don't konw what causes this, By the way, my edition is Amber10.
Thank you!!
