Run APRIL in key4hep Room: Van de Graaff/RdC-Saône Warning, use of dollar symbol provokes strange effects in the text display. So dollar symbol have been replaced in the following instructions by "dollar_symbol" in quotes. A) Running APRIL 1) source key4hep source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh ATTENTION : to work, you need a version of DDMarlinPandora compiled with the APRILContent and the SDHCL content on 2) get an ILDConfig version : e.g wget https://github.com/iLCSoft/ILDConfig/archive/refs/tags/v02-03-04.tar.gz tar xzvf v02-03-04.tar.gz cd ILDConfig-02-03-04/StandardConfig/production/ 2.1) edit the file ParticleFlow/PandoraPFA.xml add in the list of MyDDMarlinPandora processor parameters the following line : <parameter name="UseAPRIL" type="bool"> false </parameter> copy the APRILSettings_sdhcal_WIP.xml files attached to this contribution in the PandoraSettings/ directory. 3) If you don't have an input file, simulate one from the ILDConfig howto : ddsim --inputFiles Examples/bbudsc_3evt/bbudsc_3evt.stdhep --outputFile bbudsc_3evt_SIM.slcio --compactFile "dollar_symbol"k4geo_DIR/ILD/compact/ILD_l5_v02/ILD_l5_v02.xml --steeringFile ddsim_steer.py 4) Reconstruction with APRIL on SiW-ECAL+SDHCAL : Marlin --constant.DetectorModel=ILD_l5_o2_v02 --constant.lcgeo_DIR="dollar_symbol"k4geo_DIR --global.LCIOInputFiles=bbudsc_3evt_SIM.slcio --constant.PandoraSettingsFile=PandoraSettings/APRILSettings_sdhcal_WIP.xml --MyRecoMCTruthLinker.TrackCollection=VOID --MyDDMarlinPandora.UseAPRIL="true" MarlinStdReco.xml B) To install your local DDMArlinPandora with APRILContent and SDHCALContent ON : key4hep setup should have been sourced 1) clone DDMarlinPandora git clone https://github.com/iLCSoft/DDMarlinPandora.git 2) install cd DDMarlinPandora/ mkdir build; cd build; cmake -DPANDORA_MONITORING=ON -DUSE_APRILCONTENT=ON -DUSE_SDHCALCONTENT=ON .. make install 3) setup your local DDMarlinPandora cd .. k4_local_repo . 4) to run : see section A above. If you restart from a new shell, you will need to source the same key4hep setup, execute "k4_local_repo ." in your local DDMarlinPandora directory and then go back to section A. C) Modifying APRILContent and/or SDHCALContent 1) Install APRILContent : instruction in https://github.com/SDHCAL/APRILContent 2) Install SDHCALContent : instruction in https://github.com/SDHCAL/SDHCALContent 3) once installed cd APRILContent directory k4_local_repo . cd SDHCALContent directory k4_local_repo . then recompile DDMarlinPandora (see section B above)
