你好,我在用低核数的时候,界面没有变化,但命令是在运行中,用nohup命令,输出文件也没有变化,请问这有可能是什么原因?下面是平衡时的mdp文件,请帮忙看看有哪里需要整改。define = -DPOSRES -DPOSRES_FC=4000
integrator = md
tinit = 0.0
dt = 0.020
nsteps = 50000
nstlog = 1000
nstenergy = 1000
nstxout-compressed = 1000
compressed-x-precision = 100
cutoff-scheme = Verlet
nstlist = 20
ns_type = grid
pbc = xyz
verlet-buffer-tolerance = 0.005
epsilon_r = 15
coulombtype = reaction-field
rcoulomb = 1.1
vdw_type = cutoff
vdw-modifier = Potential-shift-verlet
rvdw = 1.1
tcoupl = v-rescale
tc-grps = protein solute
tau_t = 1.0 1.0
ref_t = 300 300
; Pressure coupling:
Pcoupl = berendsen
Pcoupltype = isotropic
tau_p = 5.0
compressibility = 4.5e-5
ref_p = 1.0
; GENERATE VELOCITIES FOR STARTUP RUN:
gen_vel = yes
gen_temp = 300
gen_seed = 8942579836
refcoord_scaling = all
最后停止的界面会出现LINCX WARNING,如下
