  1. Atlantis Event Display with AOD and EV ntuples Juergen Thomas* on behalf of the Atlantis team: *University of Birmingham (UK) University College London (UK) Radboud University Nijmegen (NL) Physics Analysis Tools Meeting, ATLAS Software & Computing Workshop, CERN, 23 Oct 2007

  2. Outline • JiveXML changes • Atlantis with 13.0.30 AODs • Event Properties dialog • New colour scheme • Associations of AOD objects • Interface to EventView (TopView) ntuples: Root macro • Trigger result in Atlantis • Other improvements: • User interface: Modifier keys, Anti-aliasing NOTE: Shown features are in Atlantis versions from AtlantisJava-09-08-25. Update from Atlantis Event Display CERN, 23 Oct 2007

  3. JiveXML Changes • JiveXML packages can now be configured to write out data from ‘FavouriteCollection’ and ‘OtherCollections’ in StoreGate only. • (Hopefully) reasonable default selection chosen. • HLT collections not retrieved by default. Switch: ‘DoWriteHLT’ (esp useful for Clusters and Tracks). • Updated for 13.0.30 TrigDecision (in progress) • Check dedicated TWiki about running on AODs: https://twiki.cern.ch/twiki/bin/view/Atlas/AtlantisWithAOD Method still same as in 12.0.6. Insert JiveXML-call into any AOD- reading jOs, e.g. UserAnalysis, or AnalysisCommon.TWiki also explains color coding of AOD Objects. Update from Atlantis Event Display CERN, 23 Oct 2007

  4. Event Properties • Event Properties Dialog: List of all data available in xml file • Select under ‘File’ menu • Here: From 13.0.30 AOD (note new SG keys) Update from Atlantis Event Display CERN, 23 Oct 2007

  5. AOD Objects in Atlantis (1) • AOD panels now renamed into ‘Objects’, now includesalso Jet and ETMiss • ‘Collection’: Select from drop down menu, e.g. Staco/MuID, or TauRec/Tau1p3p, Atlfast etc Update from Atlantis Event Display CERN, 23 Oct 2007

  6. New colour scheme: Extended to 32 colours • Customisable by using the Colour map editor (under ‘Preferences’) • ‘Pick’ on objects to find out what they are. • We’re working on making object label clearer (currently: Colour-coding and ‘Pick’) Your input/feedback is welcome ! • Colour scheme similar to ‘old’ one can be chosen: ‘Preferences->Colour Map->Old’ • Event shown is default from RecExCommon (semilep ttbar), 13.0.30 AOD, with ROIs and Clusters Update from Atlantis Event Display CERN, 23 Oct 2007

  7. Event shown is default from RecExCommon (semilep ttbar), 13.0.30 AOD, with ROIs and Clusters • Muon and MuonROI visible (red) Update from Atlantis Event Display CERN, 23 Oct 2007

  8. Associations in AOD objects • Associations use ‘ElementLink’ (StoreGate key/index) (recipes from Ketevi) • Following associations are implemented, using AOD colour coding: • Electron: Cluster & TrackParticle (one-to-one) • Muon: Cluster & TrackParticle (one-to-one) • Photon: Cluster (one-to-one) • TauJet: Cluster & TrackParticle (one-to-many) • To do: ParticleJet (awaiting merger with ESD Jet) • GUI: Currently ‘Electron->Show Associations’, but will change to Track->Color by Object’ resp. ‘Cluster->Color by Object’ (one switch switches all) • Updated and tested in 13.0.30 • Plan: Extend to composite particles Update from Atlantis Event Display CERN, 23 Oct 2007

  9. Interface to EventView (TopView) ntuples (1) • Normally, producing xml data for Atlantis always requires to run athena with JiveXML (e.g. with RecExCommon or UserAnalysis or EventView) • New tool: Root macro reading ntuple directly: ntupleXMLdeveloped and tested with v121302 TopView ntuples (TruthAll) • Located in graphics/AtlantisJava/share (only in cvs for distribution and code management) • Detailed instructions and documentation:https://twiki.cern.ch/twiki/bin/view/Atlas/AtlantisWithTopViewNtuples Update from Atlantis Event Display CERN, 23 Oct 2007

  10. Interface to EventView (TopView) ntuples (2) • Output from ntupleXML.h in Atlantis • Reco and Truth • Example event: semileptonic ttbar: lep W->e,nu, had W->j j • (Note: labels added from output of ‘Pick’ on objects, added into plot here by hand) Update from Atlantis Event Display CERN, 23 Oct 2007

  11. Trigger Result in Atlantis • ‘Event Properties’ Dialog now also shows: • If trigger levels are passed • L1-EtMiss and L1-SumEt • List of passed L1, L2 and EF items • Select under ‘File’ menu • Note: Numbers here from 12.0.6 AODs (old menu) Update from Atlantis Event Display CERN, 23 Oct 2007

  12. Modifier keys • Originally to allow the user to know what key to press • To improve use on laptop after feedback from the tutorial this was extended so now the user can select which modifier to use without having to use the modifier key Update from Atlantis Event Display CERN, 23 Oct 2007

  13. Other Improvements (1) • Anti-aliasing (‘smoother lines’): Tick-box: ‘Preferences->Use Anti-Aliasing’ • Off by default to improve GUI response e.g. when zooming. But normally not much slower when on. • Anti-aliasing is done after zooming to improve performance. • Full unzoom • Resets to original window zoom Update from Atlantis Event Display CERN, 23 Oct 2007

  14. Other Improvements(2) • Tick box in the read event dialog to allow the user to set this as the default event files location Update from Atlantis Event Display CERN, 23 Oct 2007

  15. HyperNews forum under category: Offline Software Development and HelpeMail Gateway: hn-atlas-AtlantisDisplay@cern.chFeedback on all old and new features is welcome For questions and feedback… Update from Atlantis Event Display CERN, 23 Oct 2007
