You can create institutional team presets in order to support multiple institutions or different groups of physicians (e.g. multiple ophthalmologists and/or radiation oncologists) within the same institution. To create an institutional Team preset:

1. In the Institution controls group, fill out the various text fields. You can also include planning notes, a preferred treatment weekday, duration, Rx dose, isodose legend and other institution specific settings. Planning notes are intended to remind the planner of institutional and/or team specific requirements. For example, an institution or team may routinely want 3 mm PTV base-margins rather than the default 2 mm margins. Notes are initially displayed in red text to attract attention. Click the "thumbs up" emoji adjacent to the planning notes text field to acknowledge having reviewed the planning notes and remove the red text color.
2. In the Team members database (n) controls group near the bottom of the window, enter a person name. (n) is the current number of names in the database. Names should be entered using the format "given name surname", e.g. John Doe, with a space between the person's given name and their surname. The + button adds people to the PSpeople.sqlite database. The - button removes the current name from the database. This database is keyed by name and also saves contact (e.g. primary email address), alternate contact (e.g. an email address that does not have email attachment restrictions), phone, job title, and other information about each person. There is no specific limit to number of persons you can add to the PSpeople database although eventually you could exceed your available file storage capacity and access speed will slow as the database size increases. A practical limit to maintain access speed and disk space is probably a few thousand.
3. In the Treatment team (n) controls group you can add up to 16 members to the team using either the popup menus (or the + buttons which copy whatever is currently displayed in the Team members controls group). (n) is the current number of persons in the team. The radio buttons select between accessing parameters for members 1..8 or 9..16. The - buttons clear the treatment team entries and the Edit buttons copy entry data back to the Team members controls group where you can edit the data and update the PSpeople.sqlite database.
4. In the Logotype controls group you can drag and drop a 50x50 pixel custom logo for each institutional preset. Logo pictures are best saved as .png files with transparent backgrounds.
5. In the Team presets database (n) controls group, enter a unique presets dictionary key and click the + button to add the keyed preset to the presets database file PSclinics.sqlite. (n) is the current number of teams in the database. Most institutions consist of a single team, but some institutions require several teams that vary amongst multiple surgeons, surgical facilities and radiation oncology staff. To remove a keyed preset, select it from the popup menu and click the - button. To update (ie overwrite) an existing preset, simply select it from the popup menu, change the information, and click the + button (same as creating a new preset). Extremely old versions of PS6 kept these data in a .plist file rather than a database, so if you are upgrading from a pre-database version of PS6 you will need to manually recreate a presets database. The .sqlite database files are all located in the application's master data folder (e.g. the Plaque Simulator Data folder).
6. Once you have created a PSclinics.sqlite database containing at least one team preset here, you may then select a default team preset in the Users Preferences pane.
