.. todo:: This command has not yet been ported to the *new APBS syntax* (see :ref:`new_input_format`).
For each molecule in the system and for each trajectory, specify a xyz file for the starting position of that molecule. The syntax is:
xyz {molecule_id} {filename}molecule_id- An integer (starting at 1) of the molecule index from the READ section
filename- The name of the file for the xyz coordinates of the molecule center for a given trajectory. The trajectories for a given molecule should be ordered sequentially in the ELEC section.
.. todo:: It would be nice to incorporate the ``xyz`` functionality into the :ref:`read_old_input` block. Documented in https://github.com/Electrostatics/apbs/issues/505
