How to generate and run a Trigger executable in the Offline

The Mu2e offline provides a dedicated python script Trigger/scripts/genTriggerFcl.py that allows the user to generate an fcl starting from a trigger configuration file. Examples of config file can be found on Trigger/scripts/inputs directory. The configuration file allows the user to set a general event prescale factor and also a second prescale factor that is applied to the good events.

To run the python script you need to use the following command:

python Trigger/scripts/genTriggerFcl.py -c myInput.config -o myTrigFcl.fcl 

where myInput.config contains the list of the trigger paths you want to include in the fcl, together with their prescale factors if needed, myTrigFcl.fcl is the name of the file that will be generated by the script.

How to get the whole list of trigger paths available

The simplest way is to run the python script with the help<\code> option:

python Trigger/scripts/genTriggerFcl.py -h
