Hi,
I want to do the molecular dynamics simulation between RNA-Protein
complex. For this I have used ff12SB force field as I am using AMBER12 CUDA
version. I have made three different input files for Heating,
Equilibration, and Production run. The input files are given below
respectively.
&cntrl
imin = 0,
ntpr = 500, ntwr = 100000, ntwx = 500, ntwe = 500, iwrap = 1,
ntf = 2, igb = 0,
cut = 10.0,
nstlim = 5000, dt = 0.002,
tempi = 0.0, temp0 = 300.0, ntt = 3, gamma_ln = 1.0,
ntb = 1, ntp = 0,
ntc = 2, tol = 0.00001,
vlimit = -1.0d0,
/
&ewald
vdwmeth = 1,
/
For Equilibration the input file is:
&cntrl
imin = 0,
ntx = 7, irest = 1,
ntpr = 500, ntwr = 100000, ntwx = 500, ntwe = 500, iwrap = 1,
ntf = 2, igb = 0,
cut = 10.0,
nstlim = 5000, dt = 0.002,
tempi = 300.0, temp0 = 300.0, ntt = 3, gamma_ln = 1.0,
ntb = 2, ntp = 1, taup = 10.0,
ntc = 2, tol = 0.00001,
vlimit = -1.0d0,
/
&ewald
vdwmeth = 1,
/
For Production run the input file is:
&cntrl
imin = 0,
ntx = 7, irest = 1,
ntpr = 500, ntwr = 100000, ntwx = 500, ntwe = 500, iwrap = 1
ntf = 2, igb = 0,
cut = 10.0,
nstlim = 5000, dt = 0.002,
tempi = 300.0, temp0 = 300.0, ntt = 1, tautp = 10.0,
ntb = 1, ntp = 0,
ntc = 2, tol = 0.00001,
vlimit = -1.0d0,
/
&ewald
vdwmeth = 1,
/
Can I use these parameters or it needs any modification?
Thanks for your consideration.
