vmd usage for dcd dump files

LAMMPS LAMMPS Mailing List Mirror

Hi,

I have been using lammps for about a month now and i decided to try and output dump files in dcd format.
I am using VMD for viewing the output. However, even though i can see that the dcd file has been loaded in the console, i can’t see any output in the display window.
Please help.

Thanks,
prateek

I think that's a VMD question. Axel to the rescue?

sure.

the answer is simple. a .dcd file contains _only_ coordinates,
so VMD doesn't know how to represent them as it needs
to assign atom types/names and so on. usually dcd files
are used in combination with a "topology" file that contains
all that information and no coordinates, e.g. a .psf file.
