Using OpenMX Viewer to visualize the molecular dynamics

Molecules and crystals can be visualized using softwares such as XCrySDen, VESTA and VMD, but sometimes there are difficulties in installing these softwares into the computer we are using, say during a workshop like the CMD workshop. In such a circumstance, it is quite useful to use web-based tools. Among others, I find OpenMX Viewer very useful. Below, I describe how to use OpenMX Viewer by using the C₂H₄ as an example.

Visit the OpenMX Viewer site:

Download your trajectory file, say, traj.xyz to your local computer, and then drag and drop your trajectory file as suggested in the web page: (In case you have difficulty in producing the trajectory file, download/copy it from here)

Then you can see the following image:

By clicking the >> botton, you can see the atoms moving.
