Hello VMD,

I would like to draw a box in order to see the edge of a crystal cell.

I saw that the plugins PBCTools can do that but I did not success in using
commands that the plugins provides.

http://www.ks.uiuc.edu/Research/vmd/plugins/pbctools/#x1-50004.1

How do I set the parameters ? What is the true syntax ? I tried different
syntaxes of

pbc set cell or set cell or pbc cell ...

I put arguments in {} or [] ... and I did not find the true syntax.

Thank you for your help

Germain
