That's what position restraints are doing.
I should amend this slightly. I assumed your
Hi
My simulation broke down and the simulation procedues are as follows.
1. center a protein molecule in the simulation box
2. put 20 ligands around the protein with genbox command
3. make sure that any atom of the ligands does not overlap on any atom of
the protein with Visulization-software.

No, you can conclude that your system is unstable. One possible reason is
atomic clashing, but you cannot say for sure. General advice on your problem

Hi
After reading the log file and watching the trajectory movies(nstxout = 1),
some molecule clashes with another in my simulation system.
How can i avoid the situation happening again?
How to modify the broken simulation?

Two options come to mind:

Hi
I print out the energy EM-solvated.edr file here.
Since the average is high, is it caused by the molecule clashing?
I selected potential, kinetic, total energy.
What else energy should I print out to learn the broken simulation system?
Thank you
Lin

It means there's something badly wrong. For the usual sort of
biomolecular MD simulation, PE should be negative, around 10^-4 to 10^-6

what does the max max 597108032.00 (between atoms 366 and 368) mean?
is it the max force or max length of the system?
where is the max force listed?

It corresponds to the length between the constrained atoms. Forces are printed
to the .trr file if you have

Here is my .out file.
atoms 366 and 368 are two atoms inside the protein.
What is other possible way to solve it ?

Hi
In the position restrain MD, only solvent molecules and hydrogen atoms are
allowed to move.
I checked the .out file.
The max is happened on the atoms inside protein.
Why?
Thank you

I am new to GROMACS, like to use it. I would be appreciate if anyone can direct
me to the right place where I could
get the linux binary either x32/x64 - redhat.
I could not compile the source cause it is looking for FFTW etc.,.
thanks

Binaries for newer versions probably haven't been made yet. Your subject line
points to version 4.0.6,
