I did what you said. Following is the message:

Reading frame    3000 time 9254.000   Warning at frame 3077. Velocities for atom 11896 are large (52568.4)
Warning at frame 3077. Velocities for atom 11896 are large (7.68295e+31)
Warning at frame 3077. Velocities for atom 11896 are large (2.75578e+23)
Warning at frame 3077. Velocities for atom 11901 are large (9410)

WARNING: Incomplete header: nr 3078 time 9408


Item        #frames Timestep (ps)
Step          3078    2
Time          3078    2
Lambda        3078    2
Coords        3078    2
Velocities    3078    2
Forces           0
Box           3078    2

Did it mean my simulation was failed? But I have checked the energy file "ener.edr", too. The energy file
seems fine. How did it happen? Can I use the date after time 9254ps?
