You won't necessarily have it automatically, depending upon what you 
want to look at. One can use the formula in that paper to compute the 
displacement of the spring, or the displacement may be expressed in 
terms of the separation of the two restrained species, which requires a 
separate calculation, performed by gmx distance. Then, one can assemble 
the plot that was shown in the paper.
