大家好:
我在使用gmx加水时提示topol.top中没有SOL组,但我确定选择的是SOL组,而且top文件中有SOL。我从头重复了一次还是同样的错误。
运行的命令为:
gmx solvate -cp 4nda_complex_box.gro -o 4nda_complex_SOL.gro -p topol.top (写错了,编辑掉了)
gmx genion -s em.tpr -p topol.top -o system.gro -neutral
输出的错误信息为:
Program gmx genion, VERSION 5.1.4
Source code file: /sws/gromacs-5.1.4/src/gromacs/gmxana/gmx_genion.c, line: 304
Fatal error:
No line with moleculetype 'SOL' found the [ molecules ] section of file 'topol.top'
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
我的topol.top文件最后部分为:
; Include water topology
#include "amber99sb-ildn.ff/tip3p.itp"
#ifdef POSRES_WATER
; Position restraint for each water oxygen
[ position_restraints ]
; i funct fcx fcy fcz
1 1 1000 1000 1000
#endif
; Include topology for ions
#include "amber99sb-ildn.ff/ions.itp"
[ system ]
; Name
LIGASE/RNA
[ molecules ]
; Compound #mols
Protein_chain_A 1
7oh_couaa 1
SOL 27968
请问有可能是什么原因呢?
