 DESCRIPTION
The command TIME_CORRELATIONS opens an environment which includes a series of subcommands to define the parameters used in the calculation.

 diffusion   OPEN   filename
compute the mean square displacements $\vert r(t) - r(0)\vert^{2}$

 divide_step  nspline
provide a number equal to nspline of interpolated points between data points.

 vacf   OPEN  filename
Compute velocity autocorrelation functions and print out results to file filename

 EXAMPLES

TIME_CORRELATIONS 
  vacf OPEN vacf.test2
  divide_step 2
  diffusion  OPEN diff.test2
END

 WARNINGS
When the the subcommand use_neighbor is used cutoff cannot exceed the neighbor lists cutoffs. Experimental - Unsupported
