Changing the name of a Level 3 trigger.

These instructions assume that you have a basic understanding of what a Level3 Trigger consists of. If you don't, please carefully read the introduction page. Here are the steps that will allow you to rename a trigger:

1. Know the old trigger name and version and what you'd like to rename the trigger!

This seems obvious, but it's worth mentioning. Be aware of the naming convention - here's a not-complete list (jonathan, is there a complete list of the guidelines somewhere that we could paste here?):

- All capitals (the gui should rename with all caps if you don't type it this way, but to avoid confusion, type it in with caps!)
- begin with L3_
- if it is a test trigger, include "test" in the name
- include values of important cut(s) (an 18 GeV central electron trigger should have both "18" and "central" in its name)

Be aware of past conventions, old versions of triggers, and retired triggers when you pick your name. If you aren't careful you may find that what you've chosen will give you a version higher than 1 of a trigger, meaning that the name you picked has been picked before. (Keep in mind the hundreds of retired triggers that you don't see by looking with the Gui!) Luckily the Gui is smart enough to not make two version 1's of a trigger, but it's wise to avoid this situation and the confusion that could result.

2. It's worth mentioning again that we're about to change nothing about the trigger aside from its name. Let's say that we want to change the name of "TEST_L3_aLL_RECO_v2" because it doesn't follow the convention of beginning with a "L3" - so we'll change it to "L3_EXAMPLE_ALL_RECO". beginnnig from the main Gui page we need to click on "Create/Edit L3 Triggers", to pop up the "Select Starting Point Page". Here we need to select the name of the trigger that we want to change from the pull down menu - here's what it looks like after TEST_L3_ALL_RECO_v2 has been selected:



We then click on "Proceed", and the "L3 Page" will pop up:



Our first step is to click on the "Insert/Edit Triggers" button, which pops up the "Show Table Data dialog":



We need to type in the new name of the trigger in the first row, "Trigger _Name:". Note that we DO NOT type in the version number! When this is finished the page looks like this:



When the name has been entered correctly (in capitals, no version) we can click on "Done" and we will be brought back to the "L3 Page" but this time the "Insert/Edit Triggers" button will be highlighted:



Our next step is to click on "Insert/Edit CLASSES", and the "L3 Option Classes Page" will pop up:



where we'll just click on "Done" since we aren't making any changes - this is to "load" the information somehow so that when we commit the trigger everything is in place. Now the "L3_option_sequences List Page" pops up:



The new trigger name needs to be entered in once again at this point in the top box. When it is done correctly it will look like this:



We hit "done" here and the L3 Page now has both the "Insert/Edit Triggers" and the "Insert/Edit CLASSES" highlighted. We now hit "Commit" and for one last time type in the correct name in the top box (again, no version number) and then we hit done.
