PyVibMS
=======

To visualize the vibrational modes calculated by xtb (via ``--hess`` or ``--ohess``), find the ``g98.out`` file which collects the vibrational modes and frequencies.

Lauch PyVibMS in a new PyMOL window, load the  ``g98.out`` file by changing the file type into **Output File (*.out)**. Change the program type from **XYZ** to **xtb (g98.out file)**, check the **Has. Vib. Info.** box, click **Load** button.

Then vibrational modes can be visualized as following
