AMBER: Fail to load the trajectory file.

Hi, all,

I have problem while I use ptraj to load the trajectory file hd5_wat.md.crd. The output is given below. It is supposed that the file is too large (about 2GB). I would like to know can I treat this file by ptraj. Or can I split it into several smaller files? Thanks.

Here is the output when I run the ptraj:

....
Initializing state: detected PBC beta angle in prmtop that is not 90.0!
Assuming this box is a truncated octahedron, angle is 109.471221

PTRAJ: Processing input file...
       Input is from file traj.in

PTRAJ: trajin hd5_wat.md.crd
Checking coordinates: hd5_wat.md.crd

Could not open file (hd5_wat.md.crd) with mode (r)

PTRAJ: trajout traj/hd5.traj pdb
