Subject: cannot deal with large trajectory?

Greetings everyone,
  When I use ptraj to deal with a trajectory, whose size is 3,891,920,081
bytes, ptraj fails to open it with the error message,
(but ptraj works fine with the trajectories in equilibrium state.)

"Could not open file (production.2ns.trj) with mode (r)
 WARNING in checkCoordinates(): Could not open file (production.2ns.trj)
 WARNING in ptrajSetupIO(): trajin production.2ns.trj, cannot open
 file..."

I run AMBER7 on IBM P690, so I'm not sure whether ptraj can deal
with large trajectory.

Thanks for any suggestion.

Best Regards, sychen.
