This exercise deals with heating a gold slab, namely the (100) reconstructed that you already simulated last time. The goal is to plot a density profile in the direction orthogonal to the slab, and to compute (using vmd) the radial distribution function g( r ) at various temperatures.
Download the 4.2 exercise into your $HOME folder and unzip it:

you@eulerX exercise_4.2$ bsub cp2k.popt -i 700.inp -o 700.out
you@eulerX exercise_4.2$ ./histo_z 700-pos-1.xyz
The output is 700-pos-1.xyz.z, a file with three columns: z, dn/dz, and the progressive integral of this quantity.

in Tk console you can:
Load a pbc.vmd file which includes the definition of the periodic box
vmd> source pbc.vmd
Draw the box:
vmd> draw pbcbox
Wrap all atoms in the periodic box:
vmd> pbc wrap -first first -last last
