我用 GenIce 做了一个 2x2x3 的简单I型水合物模型,在用 gromacs 进行能量最小化时候,出现- Fatal error:
- There are inconsistent shifts over periodic boundaries in a molecule type
- consisting of 4 atoms. The longest distance involved in such interactions is
- 2.079 nm which is above half the box length. This molecule type consists of
- muliple parts, e.g. monomers, that are connected by interactions that are not
- chemical bonds, e.g. restraints. Such systems can not be treated. The only
- solution is increasing the box size.
复制代码 这是什么原因?我查看了一下,盒子的大小是 2.4 nm x 2.4 nm x 3.6 nm,水分子模型是 TIP4P/ICE,采用 OPLS-AA 力场,从 gromacs,甲烷分子用 OPLS_066,其他的cs1.gro,topol.top 和 em.mdp 在附件里。
