群里我已经回复了,根本就不需要设盒子,应当以非PBC来跑 |
你设置的这些参数包括盒子大小都是有文献依据的吗?就做能量最小化问啥设置这么多? |
少年爱吃地三鲜 发表于 2019-6-29 11:09 谢谢回答,我刚确认了一下。截断值单位是nm,我这里用的0.3nm依然出现类似报错,这是怎么回事呢? |
你把单位搞清楚了,nm 和a gromacs的单位是什么 |
sobereva 发表于 2019-6-29 09:12 谢谢老师提醒, ERROR 1 [file ionicbox_GMX.top, line 8736]: ERROR: The cut-off length is longer than half the shortest box vector or longer than the smallest box diagonal element. Increase the box size or decrease rlist. 我放进盒子里一对阴阳离子进去就会出现这样错误提示,虽然盒子已经很大100埃,截断值已经很小0.3埃, ; LINES STARTING WITH ';' ARE COMMENTS title = Minimization ; Title of run ; Parameters describing what to do, when to stop and what to save integrator = steep ; Algorithm (steep = steepest descent minimization) emtol = 1000.0 ; Stop minimization when the maximum force < 10.0 kJ/mol emstep = 0.01 ; Energy step size nsteps = 10000 ; Maximum number of (minimization) steps to perform ; Parameters describing how to find the neighbors of each atom and how to calculate the interactions nstlist = 1 ; Frequency to update the neighbor list and long range forces vdwtype = PME rvdw = 0.3 vdw-modifier = Potential-Shift rlist = 0.3 rcoulomb = 0.3 fourierspacing = 0.12 pme-order = 4 ewald-rtol-lj = 0.001 lj-pme-comb-rule = Lorentz-Berthelot 这是我最小化的脚本,这是怎么回事呢 |
注意仔细看版头以及论坛首页的红字。我已经把你的标题“离子液体的气相模拟”改了,以后注意。 就是直接放一对阴阳离子进去。有问题直接说明报错,以及具体怎么做的,包括结构、mdp等信息 |
