明显是pbc的事,trjconv 用-pbc cluster 选复合物的组。

我想请教一下原理是什么嘞?我对pbc进行了-center -pbc mol -ur compact和-fit rot+trans
cluster clusters all the atoms in the selected index such that they are all closest to the center of mass of the cluster, which is iteratively updated. Note that this will only give meaningful results if you in fact have a cluster. Luckily that can be checked afterwards using a trajectory viewer. Note also that if your molecules are broken this will not work either.

参考GROMACS手册 https://manual.gromacs.org/current/onlinehelp/gmx-trjconv.html

老生常谈的问题,仔细看下文RMSD部分
谈谈怎么判断分子动力学模拟是否达到了平衡
