1. 27/02/04 ATLAS weekTileCal Athena tutorial, part 21 TileCal Athena tutorial Part 2: Reading GEANT hits from ZEBRA and POOL Reading HLT and testbeam ByteStream files Alexander Solodkov IHEP, Protvino, Russia

2. 27/02/04 ATLAS weekTileCal Athena tutorial, part 22 Building TestRelease  This what we did half an hour ago cmt co TestRelease cd TestRelease/TestRelease-00-00-15/cmt cmt config make../setup.sh cd../run

3. 27/02/04 ATLAS weekTileCal Athena tutorial, part 23 Preparing Job options  Copy jobOptions file get_file –jo jobOptions_TileRec.txt  Edit jobOptions file set max number events to read ApplicationMgr.EvtMax = 100; set output level to INFO (to supress DEBUG output) MessageSvc.OutputLevel = 3; Add CronoAauditor (to see time spent in algorithms) ApplicationMgr.DLLs += { "GaudiAud" }; AuditorSvc.Auditors += { "ChronoAuditor"}; Remove noise in TileCal #include "TileConditions/TileNoiseOff_jobOptions.txt"

4. 27/02/04 ATLAS weekTileCal Athena tutorial, part 24 Running Athena with ZEBRA input  Find appropriate ZEBRA file and make link to it Test file with few events ln -s /afs/cern.ch/atlas/offline/data/testfile/dc1.001003.simul.0001.test.h130 _2e2mu_extract.zebra ZEBRA.P DC1 production (jets) ln –s /castor/cern.ch/atlas/project/dc1/simul/data/002045/dc1.002045.simul. 00001.hlt.pythia_jet_560.zebra ZEBRA.P  Run Athena atena.exe jobOptions_TileRec.txt > rec1.out

5. 27/02/04 ATLAS weekTileCal Athena tutorial, part 25 Looking at the output  tilerec.ntup file contains 2 ntuples ID=30 – all TileHits (energy from PMT in GeV before sampling fraction correction) ID=70 – all TileRawChannels (energy in PMT in ADC counts)  Open ntuple in PAW and plot some distributions PAW> hi/fil 1 tilerec.ntup PAW> cd TILEREC PAW> nt/pri 30 PAW> nt/plo 30.totalE PAW> nt/pri 70 PAW> nt/plo 70.totalE

6. 27/02/04 ATLAS weekTileCal Athena tutorial, part 26 Working with ByteStream file  Copy jobOptions file get_file –jo jobOptions_WriteTileBS.txt get_file –jo jobOptions_ReadTileBS.txt  Create ByteStream file athena.exe jobOptions_WriteTileBS.txt > write1.out Output: RawEvent.re – bytestream file in T/DAQ format tilebs_write.ntup – ntuple with raw channels  Read from ByteStream file athena.exe jobOptions_ReadTileBS.txt > read1.out Output tilebs_read.ntup  Compare total energy in tilebs_write.ntup and tilebs_read.ntup Do you see difference?

7. 27/02/04 ATLAS weekTileCal Athena tutorial, part 27 If reading from ByteStream didn’t work  TileCal detector description can be initialized from 3 different sources: ZEBRA file Special ROOT Det.Descr file, prepared with every release NOVA database via GeoModel  When we read from ByteStream, we can use ROOT file (current default) or can switch to GeoModel #include "TileGeoModel/TileGeoModel_jobOptions.txt" #include "TileDetMgrDetDescrCnv/TileDetMgrDetDescrCnv_jobOptions.txt" DetDescrCnvSvc.ReadFromNova = true ;  Put all these lines in jobOptions_ReadTileBS.txt instead of #include "TDRDetDescrAthenaRoot/TDRDetDescrAthenaRoot_jobOptions.txt  … and run again

8. 27/02/04 ATLAS weekTileCal Athena tutorial, part 28 Reading Geant4 hits (preparation)  Switch to latest good nightly Logout and login again mkdir $HOME/night2 cd night2 cp../cmtwork/requirements. Edit requirements and put macro ATLAS_RELEASE "nightlies/rel/atlrel_2“.../cmtwork/cmt_init  Extract packages from CVS cmt co TestRelease cmt co Simulation/Digitization  Rebuild everything Check your quota first: “fs listacl” If too small – remove some files from your previous $HOME/cmtwork directory cd TestRelease/TestRelease-00-00-15/cmt cmt broadcast make

9. 27/02/04 ATLAS weekTileCal Athena tutorial, part 29 Reading Geant4 hits from POOL  Initialize run-time environment../setup.sh cd../run  Copy input files and XML catalog cp ~tilecal/www/General/documents/tutotial/*.xml. cp ~tilecal/www/General/documents/tutotial/*.root.  Prepare jobOptions cp../../../Simulation/Digitization/Digitization*/share/AtlasDigitization.txt. In AtlasDigitization.txt remove all non-Tile stuff and TDRDetDescrAthenaROOT, put EventSelector.InputCollection = "TileHits.root"; #include "TileRec/TileG4ToRC_jobOptions.txt" #include "TileConditions/TileNoiseOff_jobOptions.txt" // no noise for debugging TileHitVecToCnt.TileHitVector = "TileG4Hits"; // temporary fix before release 8.0.0 Copy everything you want from your old jobOptions_TileRec.txt to AtlasDigitization.txt  Run Athena unset POOL_CATALOG athena.exe AtlasDigitization.txt

10. 27/02/04 ATLAS weekTileCal Athena tutorial, part 210 Reading testbeam data  Prepare jobOptions get_files –jo jobOptions_TileTB_castor.txt Add parameters you want (see ntuple_HOWTO at http://agenda.cern.ch/fullAgenda.php?ida=a04802 in extra materials of Karl talk) http://agenda.cern.ch/fullAgenda.php?ida=a04802  Run Athena athena.exe jobOptions_TileTB_castor.txt > tb1.out  Look at the ntuple created tiletb.ntup, ntuple id=71 in subdirectory tilerec  Read ROBID_HOWTO at the same web page  Extract TileCalorimeter/TileSvc/TileByteStream package from CVS modify and compile it  Change run number in jobOptions file from 360966 to 350220 and try again

11. 27/02/04 ATLAS weekTileCal Athena tutorial, part 211 Writing new algorithm  Let’s create new algorithm in empty package cmt co TileCalorimeter/TileRec cmt co TileCalorimeter/TileAthena  Go to TileAthena package, copy several files from TileRec package to appropriate places in TileAthena cmt/requirements TileRec/TileHitToNtuple.h src/TileHitToNtuple.cxx src/components/*  Rename both.cxx and.h files to TileHitTest.*  Rename files in components directory to TileAthena*  Edit all copied files and replace all occurrences of TileRec by TileAthena, TileHitToNtuple by TileHitTest  Compile the code  Go to TestRelease/run directory and modify jobOptions_TileRec.txt Add TileAthena DLL Replace TileHitToNtuple by TileHitTest everywhere Try to run  If you have time – try to book and fill histogram with total energy

12. 27/02/04 ATLAS weekTileCal Athena tutorial, part 212 Putting code to repository  Go to your TileAthena directory and inform CVS about new files cvs add TileAthena/TileHitTest.h src/TileHitTest.cxx src/components cvs src/components/*  Edit ChangeLog files emacs ChangeLog Press control-X 4 A Write your comments below today date  Make sure that your changes are not in conflict with repository (update your files to latest version from repository) cvs update –A If there are conflicts – try to resolve them CVS puts “ >>>>>>>” around conflicting lines in the file After you resolve conflicts – try to rebuild and run again  Commit and tag cvs ci –m “TileHitTest algorithm added “ cvs tag TileAthena-00-00-01  Then, go to Tag Collector and declare your tag Before doing this make sure that your code is working with latest nightly and with all new packages which appeared after last nightly
