You need a .tpr file and can re-wrap the periodic image with trjconv -pbc

Funny, it needs a file which I don't find:

g_trjconv -f nvt_minimized.trr -o nvt_minimized_compact.xtc -pbc mol -ur
compact

Program g_trjconv, VERSION 4.5.5
Source code file: /builddir/build/BUILD/gromacs-4.5.5/src/gmxlib/gmxfio.c,
line: 519

Can not open file:
topol.tpr

If you don't specify an actual file name to -s, then all Gromacs tools look for a default file name, which in this case is "topol.tpr." Since you've run a simulation, clearly you have a .tpr file, which is what you need to provide to -s.
