MCEEP Resources

Running MCEEP

  • login to the farm
 ssh ifarm
  • a simple command will take you to the MCEEP directory (/work/halla/e07006/disk1/Erez/MCEEP/mceep)
 $GoMCEEP

(envinrinmentals are set in ~/.cshrc)

  • create a new directory for the run you want to take, and go inside it, e.g.
 mkdir v3_9
 cd v3_9
  • copy a sample input file
 cp ../input/v3_9.inp .
 mv v3_9.inp My_v3_9.inp

(and edit in)

  • a simple run command will run the simulation
 $RunMCEEP
 My_v3_9
  • choose a procedure
 ELASTIC, BOUND STATE, CONTINUUM or ACCEPTANCE
  • After MCEEP will finish running, multiple output files will appear in the output directory, the most important are a summary file and an NTuple file
 My_v3_9.sum
 My_v3_9.ntu
  • Conversion to ROOT format is then achieved by going to the ROOT utilities and using the conversion program
 cd $mceep_home/utilities/root/
 m2root $mceep_home/v3_9/My_v3_9.ntu
 mv mceep.root $mceep_home/v3_9/
 cd $mceep_home/v3_9/
  • The ROOT output file mceep.root will have a TTree called mceep with the variables set in the input file. To draw e.g. E(miss) use
 mceep -> Draw("EMISS")


comments

  • If elastic scattering is chosen, MCEEP will prompt the user to select scattering from the p, d, 3H, 3He, 4He or 12C.
  • Also, for elastic scattering in general, the user has the option of enforcing the acceptance of the hadron arm or simulating single-arm elastic scattering where the hadron kinematics are ignored.
  • If elastic scattering is chosen, MCEEP requests no further input.
  • For the bound state or continuum options, MCEEP will prompt the user to choose from various models.
