   I am trying to load amber MD files by command:

vmd apo.prmtop -rst7 m6.rst

and I get the following information for above command:

Box Dimensions are 86.454002 79.653999 100.666603 90.000000
90.000000 90.000000

when I try to type pbc box in terminal, it said:

-error Suspicious pbc side length (a=0.000000 b=0.000000 c=0.000000).
Have you forgotten to set the pbc parameters?

I also try to open periodic molecule from representation menu, but
nothing more displayed....

I am wondering what happen?

thank you very much
