Just to answer my own question:
I found the following procedure:

After the calculation run python with the following:

>>> from ase.vibrations import Vibrations
>>> from ase.io.trajectory import Trajectory
>>> traj = Trajectory('CO2.traj')
>>> mol = traj[-1]
>>> vib = Vibrations(mol)
>>> vib.summary()

Dear ASE Friends,

Ik have performed a vibration analysis. The respective calculation looks successful, but I’m left with a bunch of vib.*.pckl files.

How can I execute a vib.summary() starting from these files?
