Hi, Kyle. There’s a test to dump the ECAL LED mapping in the conditions module. cd trunk/conditions mvn test -Dtest=EcalLedTest The test code is in src/test/java/org/hps/conditions/ecal Though it uses run 0. The conditions at JLab for this are tagged with run_start of 2000. So you should setDetector(“someDetectorName”, 2000) to set this up correctly if you want to access the currently loaded LED info. —Jeremy ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
