User Test on ATLAS Graphics Packages

1. User Test on ATLAS Graphics Packages G. Cabras, M. Cobal(O), University of Udine, Italy (O) and CERN

2. Atlantis a6 1_7 GraXML 2.3.22 Linux RedHat 6.1 (Kernel 2.2.12-20) Pentium III@450MHz 128MB SDRAM@100MHz Graphic board ATI AGP w 4MB VRAM Wired 2.2 Windows 2000 (5.00.2195) Pentium III@500MHz 128MB SDRAM@100MHz Graphic board ATI AGP w 4MB VRAM Packages and HW/SWenvironments

3. Data

4. 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 -> heprep.xml not available Possible to convert to Atlantis format (but to old one)

5. 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)

6. GraXML J. Hrivnac

7. GraXML Installation • Version 2.3.22 (27 Apr 01)tested on PC Linux RedHat6.1 (Kernel 2.2.12-20 on an i686) Ver. 2.3 rapidly evolving(from /afs/cern.ch/atlas/project/graphics/Java): Aug 22 2000 Graphics.2.3.0.jar Aug 23 2000 Graphics.2.3.1.jar Aug 25 2000 Graphics.2.3.2.jar Aug 29 2000 Graphics.2.3.3.jar Aug 30 2000 Graphics.2.3.4.jar Sep 6 2000 Graphics.2.3.7.jar Sep 11 2000 Graphics.2.3.9.jar Sep 14 2000 Graphics.2.3.10.jar Sep 18 2000 Graphics.2.3.11.jar Sep 26 2000 Graphics.2.3.12.jar Oct 6 2000 Graphics.2.3.14.jar Oct 9 2000 Graphics.2.3.15.jar Oct 27 2000 Graphics.2.3.16.jar Oct 27 2000 Graphics.2.3.17.jar Nov 30 20:21 Graphics.2.3.18.jar Nov 30 20:21 Graphics.2.3.19.jar Jan 22 18:51 Graphics.2.3.20.jar Mar 14 20:45 Graphics.2.3.21.jar Apr 27 18:39 Graphics.2.3.22.jar • cp –R /afs/cern.ch/atlas/project/graphics/Java [swinstallpath]

8. GraXML Test setup • Setup instructions Follow http://atlas.web.cern.ch/Atlas/GROUPS/GRAPHICS/Texts/Documentation/GraXML/#How to Start Instructions: $ sh $ cd [swinstallpath] $ . ./setup.sh $ ./GraXML.sh Examples/EndcapEvent.xml • References: http://atlas.web.cern.ch/Atlas/GROUPS/GRAPHICS/Texts/Documentation/GraXMLfor sw, and atlas xml events

10. 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

16. 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

17. Atlantis H. Drevermann N. Kostantinidis

18. 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/Atlantis/atlantis distribution! • Installation instructions (from /afs/cern.ch/user/k/konstant/public/atlas/cvs_instructions.txt): $ setenv CVSROOT :pserver:atlantis@pcatlas136.cern.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 OS=Linux $ gmake -f Makefile.abf90 OS=Linux dist_clean • Compiled with Fortran Compiler g77

19. Atlantis Test setup • Work area: $ mkdir work # atlantis work area $ cd work $ ln -s [swinstallpath]/atlantis_a6.Linux atlantis $ ln -s [swinstallpath]/ATLANTIS* . $ ln -s [eventpath]/atlantis.LAFb_* . #data events $ ./atlantis #run atlantis in a Xwindow • References: • http://hepunx.rl.ac.uk/atlasuk/simulation/level2/doc/ctrig/atlantis.html(some html pages reference afs files: fine if your host is an afs client!) • /afs/cern.ch/user/k/konstant/public/atlas/getstarted.ps • /afs/cern.ch/atlas/project/Atlantis/loomis/events/atlantis for events

21. 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

25. WIRED M. Donszelmann C. Loomis J. Perl

26. Wired Installation • Version 2.2(27 Apr 01)tested on PC/Win2000 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: http://wired.cern.ch/for sw tutorial and atlas heprep evts /afs/cern.ch/atlas/project/Atlantis/loomis/events/wired for events

29. 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

31. Full event

33. 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
