在使用amber的GAFF力场是遇到一些问题,GAUSSIAN已经生成RESP电荷文件,acpype -i Lig.mol2也转换得到了Lig_gmx.itp。但是在gromacs里调用itp却报错Invalid order for directive atomtypes,尝试了一些方法,未成功解决。有人可以给些参考性的意见么?
As indicated above, these new types and parameters must appear before any [moleculetype] directive. The force field has to be fully constructed before any molecules can be defined.看到这个提示,但是没处理正确。
