Hi, Axel and Olaf,
I'm sorry I still have to ask these simple questions about displaying box in VMD. I confirmed I have installed the latest version 1.8.7 and pbctools included in it. I read the documentation and tried to carry out the examples. Unfortunately, when I just run the pbc set cell command like the example " pbc set 10.0 10.0 10.0 -all", the errors occured. The error is like"ERROR: pbcset: unknown option: 10.0". Is this because of the command with the unknown format? I just want to set the cell and draw the celll. Why can't I use the commands "pbc set " and " pbc box"? Could you help me fix it? Thank you so much!
Lan

But, sort of, not like this. I tried to use draw_pbc_vectors and I failed. I'm not familar with tcl code. So, I don't clearly know about the arguments in each command of pbctools. I know, it is easy to draw the defined box in OPGL. using lines to connect the defined points of the specific box can generate the box image (i.e. rectangular box or cubic box). I think the tcl codes in pbctools should have described how to draw. Unfortunately, I don't know how to use these commands. I guess I must miss something. Could anyone give me some suggestions? Thanks a lot!

As Axel didn't mention where: The documentation of the pbctools plugin
that is included in VMD 1.8.6 and 1.8.7 can be found here:
http://www.ks.uiuc.edu/Research/vmd/plugins/pbctools/
If I assume that you have one of these versions, it should be enough to
type "pbc box" in your Tk console to generate the box you want.
Best regards
Olaf
