Discover - MD trajectories - frame substraction, animations

Hello,

Could anyone tell me how to extract frames from the Discover molecular dynamics trajectory files?

I have the output file (let's say *.arc or *.his file) with the coordinates and energy written inside. How to find and visualize the lowest energy conformation or any other selected frame? Is it possible to perform some visualization of the molecular dynamics evolution?  I have no idea how to do it. I found an old manual from 1997 for CDDiscover with Cerius2. There is a very detailed description how to display the single conformations and create the animations, but I cannot use the same function in Material Studio 4.2. Any suggestions please?

Greets!
