体系里涉及的moleculetype太多,应当说明每个都对应什么
如果有的moleculetype里包含多个分子,应当每个分 ...

你把盒子改成立方的试试呢?

用gmx density会直接报那种错误?按理说不太可能

Fatal error:
There are inconsistent shifts over periodic boundaries in a molecule type
consisting of 51772 atoms. The longest distance involved in such interactions
is 20.082 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.
