Quick Start
- Copy /work/halld/home/sdobbs/jpsi_mc
- To load software configurations, use setup_jlab.csh script, e.g., "source setup_jlab.csh"
- Optional, check out your own copy of latest software and build it:
- HDDS geometry package: svn co https://halldsvn.jlab.org/repos/trunk/hdds
- sim-recon: svn co https://halldsvn.jlab.org/repos/trunk/sim-recon
- Designate local build area by setting HALLD_MY
- J/psi event generator: svn co https://halldsvn.jlab.org/repos/trunk/home/sdobbs/bggen_jpsi - place in local build area
- Build/develop plugin: /work/halld/home/sdobbs/halld_my/plugins/ccbar_recon
Simulations
Example files are located at:
/work/halld/home/sdobbs/jpsi_mc/
The simulation chain looks like the following:
bggen_jpsi hdgeant mcsmear hdgeant.hddm hd_root -PPLUGINS=analysis_plugin hdgeant_smeared.hddm
Where
- bggen_jpsi generates the 4-vectors of the reaction. It is one of the many generator programs that does so. Its configuration file is "run_jpsi.ffr", which must be softlinked to "fort.15".
- hdgeant simulates the path of the generated particles through the detector using GEANT. Its configuration file is "control.in".
- mcsmear simulates the response of the detector
- hd_root is the main analysis program
Notes:
- When analyzing simulations (e.g. running hd_root) you should set the environment variable JANA_CALIB_CONTEXT in the following way: (setenv JANA_CALIB_CONTEXT "variation=mc")
- There's current a bug in the code for certain run values. The current example files use run 1501.
