I performed an MD simulation in gromacs and I'm trying to plot the graphs using xmgrace with the /*.xvg files, however I can't get it in any way. Xmgrace opens but always without the graph. I am using the following command:

~$ xmgrace <file.xvg>

Any suggestions as to what the problem might be?

I'm using Grace version 5.1.25.

Thanks in advance!
