 Next, we can read in the 3D arrays containing the coordinates, forces, and deformations either at a single time step (top; A) or all time steps at once (bottom; B).

 Next, we can use matplotlib to plot and examine the timelines. We look at the contractility, which gives us a measure of all the force vectors pointing to the epicenter of the force field.
