Dear all,
I have a trajectory file generated by gromacs-4.5.5. Recently I tried to
plot radial distribution function using 'gmx rdf' tool available in
gromacs-5.1. But I am getting the following error.
Error in user input:
Invalid command-line options
  In command-line option -f
    File 'system.xtc' does not exist or is not accessible.

I knew that gromacs old trajectories can be analysed using new version
tools. But why I am facing this error?
