  1. Interactive athena vertexing with Atlantis Qiang Lu, Juergen Thomas, Peter Watkins (Birmingham) Hans Drevermann (CERN) Andrew Haas (Columbia) Eric Jansen, Pieter Klok, Charles Timmermans (Nijmegen) Simon Dean, Nikos Konstantinidis, Zdenek Maxa (UCL) PAT meeting, software week, 07/12/05

  2. Interactive atlantis/athena • Use case: “I see in my display three tracks, which look like coming from a sec. vertex. I want to fit a vertex with the athena vertexing tool” • This is now possible: • Atlantis connects to interactive athena via XMLRPC and takes over the command prompt • Atlantis transmits the indices of the tracks to fit, to the VxWrapperTool (athena AlgTool) • VxWrapperTool calls the athena vertexing tool and stores the sec. vertex to StoreGate • Atlantis requests the event data and gets the new vertex info (could be done automatically behind the scene) http://cern.ch/atlantis

  3. Vertexing wrapper tool • Interface includes • fitAtlantisTracks( std::vector<int> tracks ) • fitTracks( std::vector<const Trk::Track*> tracks ) • JobOptions • VxToolName: the athena vertexing tool • TrackContName: the track container key in StoreGate • Needed for interactive analysis (independently of atlantis) http://cern.ch/atlantis

  4. Interactive atlantis/athena (cont.) Pick tracks to make list Interactive athena control Vertexing in athena http://cern.ch/atlantis

  5. Useful tips/links • Atlantis is part of the ATLAS software release since 11.1.0 and 11.0.2 • atlantis / atlantis_beginner (full / basic functionality) available when you set up your athena environment • Documentation/tutorials etc on • http://cern.ch/atlantis • https://uimon.cern.ch/twiki/bin/view/Atlas/WorkBookAtlantis • JiveXML help on • http://www.hep.ucl.ac.uk/atlas/JiveXML/JiveXML.shtml • General help/feedback/requests/complaints to • atlantis.support@cern.ch http://cern.ch/atlantis
