[gmx-users] Error when execute g_energy - the message: not recognized, maybe different CPU?

[Rodrigo Faccioli]

Hi,

I have an error when try to execute the g_energy program. I'm using Gromacs
4.5.3 version. My Operation System is Ubuntu 9.10.

Firstly, my apology if my question is basic, but I'm a computer scientist
trying to understand the Gromacs concepts for simulation.

My error message appears when I execute the command line: echo '-e' '10' |
/usr/local/bin/./g_energy -f /home/faccioli/Execute/EESC_AE/1BDD/energy.edr
-o /home/faccioli/Execute/EESC_AE/1BDD/energy.xvg
-------------------------------------------------------
Program g_energy, VERSION 4.5.3
Source code file: /home/faccioli/gromacs-4.5.3/src/gmxlib/enxio.c, line: 772

Fatal error:
Energy file /home/faccioli/Execute/EESC_AE/1BDD/energy.edr not recognized,
maybe different CPU?
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
------------------------------------------------------

In [1] contains all files which I used in  my simulation including the
energy file (energy.edr) and all commands which I ran (_run_gromacs.txt).
The error message appears when try to execute the 2.pdb file. The others
(0.pdb and 1.pdb ) I can get the energy value. These pdb files were build
using my implementation of Nerf algorithm [2] which converts dihedral angles
to Cartesian coordinates.

I looked at line 772  of gmxlib/enxio.c file. However, I didn't understand
to fix my problem. I understood my file is not empty, but it is corrupted.
So, I couldn't understand how can it is corrupted.
