Data

Initial goal take a simple tt fully simulated
event look at it with the
various graphics packages evaluate
performances BUT. The 3 packages requires
DIFFERENT data format GraXML
.xml WIRED
.heprep.xml Atlantis
.lafa, .lafb, .LAFb
Converter xml -gt heprep.xml not
available Possible to convert to Atlantis format
(but to old one)

• Data pool found in
• /afs/cern.ch/atlas/project/Atlantis/loomis/events/
  
• Several events
• (3 directories for GraXML, WIRED and Atlantis
  format)
• Only one event available in the 3 formats
• (with different names..)
• Event_Y27346.151.2.xml (GraXML)
• Event_Y27346.151.2.heprep.xml (WIRED)
• Atlantis_lafa_60 (Atlantis)

• Clearly done for a 3-D representation of objects
  or for
• VERY simple events and detector description
• Not suitable for complex events (program does
  not even
• succeed to read them)
• Slow with used setup (expecially TRT)
• Enough user friendly (info on WEB quite clear)
• Nice windows setup
• Inner detector muon implemented
• Some points to be improved...

11
Window stays in the corner and cannot be
controlled!
12
TreeView
Too slow to apply a selection!
Option which should be a default!
13
Tracks info superimposed
What is for?
14
Colours randomly chosen Sometimes all display
comes out with the same tone! User cannot
associate colours with elements without changing
and recompiling corresponding class

• Some other small problems
• Did not succeed to print out a jpg file of the
  display
• (comes out only a gray figure)
• Also one cannot choose where to put the output
  file
• Event or elements cannot be de-selected
  immediately
• after selection (you need to click once
  elsewhere)
• Picking elements does not always work properly
• Each new file requires to re-open the program

Atlantis Installation

• Ver. A6 rev. atlantis-1_7 (23 Apr 01)tested on
  Linux RedHat6.1 (Kernel 2.2.12-20 on an i686)
• not the current /afs/cern.ch/atlas/project/Atlan
  tis/atlantis distribution!
• Installation instructions
• (from /afs/cern.ch/user/k/konstant/public/atlas/
  cvs_instructions.txt)
• setenv CVSROOT pserveratlantis_at_pcatlas136.cer
  n.ch/localdisk/hansd/cvsroot
  
  cvs login (Give "evtdisp" without
  the quotes as the password)
  
  cvs checkout -r
  atlantis-1_7 atlantis
  cd atlantis
  gmake
  -f Makefile.abf90 OSLinux
• gmake -f Makefile.abf90 OSLinux dist_clean
• Compiled with Fortran Compiler g77

• Can do everything provided you know how to do it
  !
• Files of instructions on how to get started not
  enough
• On-line help useful when you have already some
  hints
• At the moment is the most complete program but
  needs
• tutorial from expert (unless you enjoy
  riddles)
• 3 hours of phone-tutorial given by H.
  Drevermann
• Philosophy behind clearly driven by physics
  (this
• experience should not be lost!)

22

• Nice features
• Pre-defined window sets
• Not space-consuming menu (displays take most of
  the screen)
• Appealing graphics style (colours, lines,
  marks...)
• Tracks info colour linked with tracks colour
• Possibility of two-letters command strings
• To be improved
• Picking sometimes is not trivial
• Default r-z view too busy

23
Filter on Pt and d0 applied
24
Tracks with high d0 and at distance to the event
z-vertex

• Ver. 2 rapidly evolving
• April 27th 2001 - Version 2.2 released, including
  a tutorial
• April 4th 2001 - Version 2.1 released, compatible
  with JAS 2.2.3
• March 30th 2001 - Version 2.1 delayed until the
  JAS 2. 2.3 release.
• March 9th 2001 - Version 2.0.1 released, with bug
  fixes and new features
• January 26th 2001 - Version 2.0 released.
• Installation instructions
• Follow http//wired.cern.ch Instructions to run
  Wired as a plug-in module inside JAS (Java
  Analysis Studio). You need
• jdk1.3.0_02 from http//java.sun.com/j2se/1.3/
• JAS2.2.3 from http//www-sldnt.slac.stanford.edu
  /jas/downloads.htm
• http//wireddoc.web.cern.ch/wireddoc/releases/2.2/
  wired-jas-plugin.jar

27
Wired Test setup

• Wired as a JAS extension
• Run JAS, in Menu Job/Load Plugin enter Class
  hep.wired.WiredPlugin
• (for Wired 2.0.1 or previous enter Class
  hep.wired.graphics2d.App instead)
• References

• Great improvement with the latest version.
• Many functionalities now available (i.e
  picking, Z-vertex
• finding, filter for tracks and hits, hits
  grouping, V-plots etc..).
• Definitely user-friendly (and good PDF manual to
  start with)
• Goes in the same direction of Atlantis for what
  concern
• functionalities
• ( on the other end, Atlantis is going to appear
  in a Java
• version, using a significant portion of the
  Wired FreeHep
• library.....)

30

• Nice features
• Objects once selected appear coloured in all
  windows
• (all the rest turn grey)
• To be improved
• Control menu takes too much space (displays are
  sacrificed)
• Windows to be adjusted
• Default graphics style not optimised (colours,
  lines, marks)
• Not all views yet implemented
• Automatic Z-vertex calculation not implemented
• Selected tracks sometimes covered by grey ones

Preliminary conclusions
34

• Although publicly available information is
• sometimes not enough, developers very friendly
  
• and willing to help
• Maybe to soon to make a final physics-oriented
  
• evaluation packages are in continuous
  development,
• more or less only inner detector is present
• However regular monitoring and Feed-back
• between graphics developers and users (physics
  
• groups) useful.
• Two efforts (Atlantis in Java and WIRED) going
• on in parallel. Need coordination
