[lammps-users] vmd to visualize .dcd or .xyz file

dear lammps users,

     I wrote output as .dcd or .xyz files and load them to VMD. However,
the VMD complained my output file and cannot load correctly. I have
attached the dump files and the lammps script below. Can anyone tell
me what's goes wrong?

thanks

a) what are the error messages? my crystal ball is still in
   repair and thus i cannot see what you are seeing. how
   should anybody be able help you when you don't provide
   and debug info. when you go to the doctor you don't just
   say that it hurts, but you tell him where and how and
   when it started and how bad it is and so on, don't you?

b) in order to reproduce your problem, one would need either
   access to a _complete_ and working input or access to the
   files that you have produced.

i have been using both .xyz and .dcd output in LAMMPS a lot
and they worked fine for everything that was expected.

cheers,
   axel.
