I am doing a simulation on liquid argon and using PBC(default in gromacs)
on it. When I load the trajectory in vmd and construct a box using `pbc
box` it is a constant for my simulation.
Now, I want to calculate the dimensions of this box.
I tried using `pbc get -now` and got this:
{77.394997 77.394997 77.394997 90.000000 90.000000 90.000000}

I dont understand what are these the coordinates of, especially because
when i open the coordinates files it has values ranging from 0 to
approximately 8 nm.

Can someone explain this output or how to obtain the dimension of my PBC
box ?
