Thank you very much for the reply...
gmxcheck of my out shows a "segementation fault" in the last part. What could
be the problem??
this is the last part of the output
x[31416] (-7.37978e-03 6.79718e+00 6.07531e+00) - (-7.40000e-03 6.79720e+00

5.74540e+00)
Segmentation fault
The energy minimisation & the equilibration steps are finished at 15 step
eventhough it was given for 20 ps(10000 steps).But the output coordinates file
doesnt show any abnornmality as i checked in the viewer? My equilibration step was
in NVT.
whether nothing is happening or any other problem?
If you got 15 steps when you expected 10000, it seems pretty clear to me that
something crashed very early on in your simulation.

Hi,
after equlibration of my protein and ligand I tried to create the energy file ans well as the to display the trajectories using ngmx option,. But it shows the follo: error,
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Can't connect to X Server.
Check your DISPLAY environment variable
Seems like your X environment is somehow not properly configured.
If you are working through ssh, then you can :
$export DISPLAY=<your current computer's ip>:0.0
Or you are tunneling through a SSH connection. There are several
possiblities:
1. Try ssh -X to login, this could solve the problem, if you are in
principle allowed to use X11 tunneling.
2. In case this does not work either it can be that you are not allowed
to tunnel X11.
However take care that you also need a properly configured XServer
running on your own system not just on the host you login. So in case
you use Windows or MacOS make sure this is the case.

also the g_energy command shows that ,
Program g_energy_mpi, VERSION 3.3.3
Source code file: enxio.c, line: 239
Fatal error:
Energy file eq_2ps_ener.edr not recognized, maybe different CPU?
What does gmxcheck tell you about the file. Perhaps it has been corrupted in some way.
Also, you may want to work with a more current version (4.0.5) to utilize the newest features and bug fixes.

Can any one help me, please???
