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.

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)

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

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

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

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)

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)

‘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)
Trigger Result in Atlantis

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

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

Other Improvements(2)
Tick box in the read event dialog to allow the user to set this as the default event files location
