G2P REPLAY GUIDE (also available at /w/halla-1/g2p/AnalysisTools/analysis_guide)
How to start:
1. Directory structure
/w/halla-1/g2p Main g2p working directory /w/halla-1/g2p/user_name/ Directory for each user, have to be created by user /w/halla-1/g2p/software/ Directory with geant4, XercesC, coda, CLHEP etc. /w/halla-1/g2p/AnalysisTools/ Directory with main tools for analysis. /w/halla-1/g2p/AnalysisTools/analyzer/ Directory with analyzer, analyzer DB, environment setup. /w/halla-1/g2p/AnalysisTools/replay/ Directory with replay scripts. /w/halla-1/g2p/AnalysisTools/batch_farm/ Directory with batch-farm scripts.
2. Replay scripts.
Replay scripts will be located in the /replay/ directory as <replay_name>.C. *.cdef - define cuts, that will be done on replay level. *.odef - define output (tree variables, histograms etc.)
3. Environment setup.
Environment setup for root and analyzer, for geant4 see geant4 setup. > source /w/halla-1/g2p/AnalysisTools/analyzer/sourcethis.csh > or add this command to .cshrc at end of file in ~ to permanently setup environment.
4. To start work.
4.1. Create your own directory inside /w/halla-1/g2p/
> ssh ifarml64
> cd /w/halla-1/g2p/
> mkdir user_name
4.2. Required** structure:
user_name/replay/ --- copy to here everything from "/w/halla-1/g2p/AnalysisTools/replay/"
user_name/batch_farm/ --- copy to here everything from "/w/halla-1/g2p/AnalysisTools/batch_farm/"
> cd user_name
> cp -r /w/halla-1/g2p/AnalysisTools/replay/ .
> cp -r /w/halla-1/g2p/AnalysisTools/batch_farm/ .
a. make changes to def.h in replay/
default output is ./Rootfiles, ./ScrachROOTfiles, ./summaryfiles.
default output directories are found in def.h, change if you'd like.
b. make changes in .odef (for different output), in .cdef(for cuts)
**This structure is required if you will be using 'gofarm' and 'farm_cache' in batch_farm directory
4.3a. Replay run:
> cd /w/halla-1/g2p/user_name/replay/
> analyzer <replay_name>.C
raw file has form: g2p_#####.dat.**, where ##### - run number and ** - suffix (0, 1, 2 ...)
a) you will be asked for run_number
b) you will also be asked for the number of events (enter -1 to analyze all events)
4.3b Alternatively Replay can be submitted to Batch Farm (recommended):
> cd /w/halla-1/g2p/user_name/batch_farm
> read batch_farm_guide for instructions.
You should now have the rootfile in the directory you specified as output (default is /user_name/replay/Rootfiles/).
4.4. Analyze data.
> cd <output_directory>
> analyzer g2p_#####_**.root
##### - run number, ** - suffix.
--examples--
analyzer[0]> T->Draw("L.s2.la[0]") ---- Draw L.s2.la[0] variable
analyzer[0]> T->StartViewer() ---- Shows Tree structure
**** Variable definitions are available at http://hallaweb.jlab.org/podd/doc/variables.html ****
5. Runs
To obtain runs for analysis use farm_cache or farm_cache_single. > cd /w/halla-1/g2p/user_name/batch_farm/ > read batch_farm_guide for more information.
