Dear Sir, I finished my simulation with gromacs, but whatever orders I use to analysize the results, I always get errors. For example, when I type: g_density -f md.trr It returns:
Program g_density, VERSION 3.3.1 Source code file: gmxfio.c, line: 706 Can not open file: topol.tpr When I type: g_energy –f md.edr –o potential.xvg It returns: Program g_energy, VERSION 3.3.1 Source code file: statutil.c, line: 799 Invalid command line argument: –f When I type: g_rms –s md.tpr –f md.trr –o rmsd.xvg It returns: Program g_rms, VERSION 3.3.1 Source code file: statutil.c, line: 799 Invalid command line argument: –s When I type: g_gyrate –f md.trr –s md.tpr –o gyrate.xvg It retures: Program g_gyrate, VERSION 3.3.1 Source code file: statutil.c, line: 799 Invalid command line argument: –f I totally have no ideas about these error. I didn't get error information when I do the simulation. I should I do with this situation? Thanks!

It is sort of unphysical.
