Galaxy Best Practices and Troubleshooting

Listed below are best practices for using Galaxy. These are the steps that OIT has determined provide the best user experience.

• Start with a fresh browser session each day. Close your browser at the end of the day (or close and reopen it at the start of your day).
• Use the links to Orion or Gemini at utdallas.edu/galaxy, rather than bookmarks.
• Use direct links received in email for the one-time purpose it is intended for. Please do not bookmark these links for regular access
• Students should always use the Orion link. Faculty performing academic functions (like submitting grades, viewing class rosters, etc.) should also use the Orion link.
• Staff accessing HR or finance data should use the Gemini link. If you are not an employee (receiving a paycheck from UT Dallas) you likely will be unable to use the Gemini link.
