Hi Rui,
Hm, you do not say what precisely did not work. The file that you give G4 needs to be an unperturbed particle distribution (for example a glass), scaled to the correct boxsize and with the right particle mass. I've just tried it generating such a file with the attached script, and it worked for me.
Regards,
Volker
