Hello,

I'm a complete VMD newbie (I'm using the Mac version,) so this question is probably pretty basic. I can load xyz trajectory files for a periodic system into VMD, but they do not contain the unit cell dimensions. The manual says I can set these via the command line, so I have been trying to figure out how to do it. The only thing I have tried that doesn't give me an error message in the command window is something like this:

set alpha 90

It accepts the command, and prints out a value of 90. However, when I go back to the periodic tab in the Representations window, I still get no response when I try to add periodic images.

Can anyone tell me what my commands should be?

Thanks!

Barry
