Hi Karteek,

I'm using NAMD and this is how I load a traj file (DCD) with its structure
file in scripts.
*mol load psf $psf_file dcd $dcd_file*
According to the link below, it seems like VMD doesn't natively understand
lammps traj files. So you can convert your traj file
one of the supported formats given in the link and load them as above.
