How to Guide for analysis code
[last updated July 11, 2019]
Everything should be performed in digios/analysis/working directory,
- .txt file extension is editable for user.
- .dat file extension is not supposed to be edited, they are generated.
How to process run?
working>./process_run [RUNNUM]
The bash script will download run [RUNNUM], merge, event building, mapping, and Monitors.C
to see more options, ./process_run without any argument
working>./process_run
How to process multiple runs ?
edit ChainMonitors.C
you can see it use the TChain class.
to add files, for example, add the run 33 to 40, 42, 45, and 50
chain->Add("../root_data/gen_run03[3-9].root");
chain->Add("../root_data/gen_run04[0,2,5].root");
chain->Add("../root_data/gen_run050.root");
Then, in process_run
working>./process_run 50 1 1 1 2
Notice that it will download run 50 ONLY.
How to change the array position ?
edit the file detectorGeo.txt
How to change the calculation for Ex and thetaCM ?
edit the file reactionConfig.txt, than recalculate the reaction.dat by running ../Cleopatra/Transfer
working>../Cleopatra/Transfer
How to change the kinematic E-Z line?
see #How to simulate the kinematics?
The E-Z lines are stored in fxList in transfer.root
In Monitors.C, at the end or Monitors::Terminate().
you can see the code call fxList.
How to simulate the kinematics?
edit
- reactionConfig.txt
- detectorGeo.txt
- Ex.txt
Then run
working>../Cleopatra/Transfer
after that, 2 files will be generated, 1) reaction.dat, 2) transfer.root
a tree is inside transfer.root.
you can see the tree branches by
root> tree->Print()
(I know some variable names are confusing, and I will update them soon)
