这是我前面执行过的语句： 1；pdb2gmx -f 1AKI.pdb -o 1AKI_processed.gro -water spce 2; editconf -f 1AKI_processed.gro -o 1AKI_newbox.gro -c -d 1.0 -bt cubic 3; genbox -cp 1AKI_newbox.gro -cs spc216.gro -o 1AKI_solv.gro -p topol.top 4;grompp -f ions.mdp -c 1AKI_solv.gro -p topol.top -o ions.tpr 我是一个超新手，以前没有任何分子模拟的经验，也没有学过相关课程。今天下午我又重新操作了一遍，执行到第四句时出现了新的错误：no molecules were defined in the systerm.我崩溃了！这个教程我已经弄了快一星期了，就是卡在第四句上。求指点! |
