Content of this distribution

• build
  the above mentioned interface / replacements routines
  More detailed description see below
• bin
  the 32 bit binary grope.exe
• cernlib32
  sym link to 32 bit cernlibs (e.g. /usr/lib/cernlib/2006/) Must be adjusted to your enviroment
  A tarball with the needed libs (2006 edition) is provided (see above)
• root32
  sym link to 32 bit root installation Must be adjusted to your enviroment
  A tarball with the latest edition (5.34.03) is provided (see above)
• geant (->geant321)
  Makefile , car, cra, lib, src
• gopal (->gopal14)
  Makefile , car, cra, lib, src
• rope (->rope420)
  Makefile , car, cra, lib, src
• lib
  libgfortran.so.3, libftgl.so.2 (only needed on 64 bit Ubuntu)
• data
  
  • sample data files (fxddst) from OPAL with preselected events (multihadron, electron, muon, tau, cosmic) constants and bank documentation files
  • fort.4 default FFREAD cards e.g. $GROPE/data/p62electron.fxddst
    Caveat:
    We are in the old FORTRAN world, $GROPE must not get longer than 50 chars, since the complete FFREAD card must fit in CHARACTER*80
  • OPAL and OD Primer
    
  • opal.C:
    The OPAL detector geometry as defined in GOPAL converted by g2root using ROOTs TGeom package. (This does not belong to GROPE, its added for convenience)
    In a root session you can do:
    .L opal.C
opal("XY") // xy View
opal("BOX") // View from 30., 30 degree with a box cut out
  
  Files in top dir:
  

• iniRopePath.sh
  set PATH and LD_LIBRARY_PATH for building and running Note: Entries might depend on the local installation paths and may need to be adjusted
• Makefile
  compiles routines in build directory and links grope.exe

Description of interface / replacement routines in build

• grope.f
  GROPEs main program generated from grope.cra In SUBROUTINE USINIT the file with FFREAD cards is explicitly opened either:
  $PWD/fort.4
  or
  $GROPE/data/fort.4
• dislan.F
  OPAL uses a special routine for the Landau distribution
• finame.o
  This is only to help the linker, it is extracted from libfi607.a
• evget_dummy.F
  A dummy for access to OPAL data on no longer existing SHIFT
• for2c.f
  Interface C++ -> FORTRAN to overcome e.g. the difference of represention of char strings
  Intercept the output routine "odpbkx": print block
  Intercept the HIGZ routine "Query locator"
• gphigs2root.cxx
  Replacement of GPHIGS, mostly dummies
• kuip2root.cxx
  Replacement of KUIP
• higz2root.cxx
  Replacement of HIGZ, HPLOT, HBOOK
• ropecmds.cxx
  A user interface based on ROOT and CINT It may be used as pure commandline tool or from the menus implemented with a toolbox from the Marabou project (TGMrbValuesAndText)
• init.cxx
  Initialize root and the main canvas for the event display Provide a simple command button interface a la KUIP
• TPol3D.cxx
  This simple class is the key element for the replacement of GPHIGS; It is a TPolyLine3D with 4 additional field values:
  • the structure number of the graphics element given by GROPE (popst_)
  • the pick identifier
  • the name given by OD + track/cluster number (e.g. OD__CTRK_3)
  • title = name + momentum value
This implements the functionality of Pick:

• Hoovering the mouse pointer across a track or cluster prints its name + momentum value
• Right mouse gives a context menu allowing e.g. fully documented printout of track parameters.

• TGMrbValuesAndText.cxx
  A general purpose routine to simplify building a user interface with input fields, comboboxes, checkbuttons etc. from the Marabou project (http://www.bl.physik.uni-muenchen.de/marabou/html/).
