[交流] [交流讨论]关于膜蛋白能量最小化的问题

[交流讨论]关于膜蛋白能量最小化的问题

请大家帮忙,非常感谢!
我的体系是由四部分的离子通道膜蛋白加DOPC双层膜组成,选择gromacs力场,进行能量最小化,也就是第一个mdrun时,有以下出错信息:
Range checking error:
Explanation: During neighborsearching, we assign each particle to a grid
based on its coordinates. If your system contains collisions or parameter
errors that give particles very high velocities you might end up with some
coordinates being +-Infinity or NaN (not-a-number). Obviously, we cannot
put these on a grid, so this is usually where we detect those errors.
Make sure your system is properly energy-minimized and that the potential
energy seems reasonable before trying again.

Variable ci has value -2147483648. It should have been within [ 0 .. 24389 ]
Please report this to the mailing list (gmx-users@gromacs.org)

怎么回事啊?

我的蛋白pdb是下载的,应该没有啥问题吧,而且以前不加膜跑过很多了!

If initial structure have bad contact,it's easy to cause thus problem.U should check your structure carefully.

It is obvious that ur system does not well energy-minimized.
