Unfortunately, there isn't a tutorial or guide available to create a broken symmetry using Schrödinger Jaguar, but you can obtain one if you contact the developers. You can get in touch with them using the contact information from the official web page. Also, even if in the official user guide you can't find the steps to create a broken symmetry, you can find useful instructions that will allow you to get familiarized with all Schrödinger Jaguar functions.
