- From any terminal ssh username@login.jlab.org
- ssh ifarm

The SBS work directory is located at /work/halla/sbs
- Created a directory here with mkdir username
- If you do not have permission contact Ole Hansen (ole@jlab.org) and ask to be added to the SBS user group.

source /site/12gev_phys/softenv.csh 2.5
source /work/halla/sbs/ANALYZER/install/bin/setup.csh

This will set up the proper environments for using the analyzer
If you want to set up your own personal analyzer you can look here https://github.com/JeffersonLab/analyzer

If you do not plan to make changes to the replay code you can simply use the version located at /work/halla/sbs/SBS_OFFLINE and /work/halla/sbs/SBS_REPLAY
The SBS analysis is located at https://github.com/JeffersonLab/SBS-offline and https://github.com/JeffersonLab/SBS-replay
- You can copy the github versions to your own work directory, if you plan to test changes to the analysis

Follow the README instructions on https://github.com/JeffersonLab/SBS-offline to install SBS-offline.
After installing, there should be a directory, install/run_replay_here
Inside there should be one file named .rootrc (it is a hidden file).
Wherever you run the replay, this file must be there to load the SBS-offline libraries. Either run your replays here, or move the .rootrc file to the new destination.

All raw EVIO files from GMn are on tape at /mss/halla/sbs/raw
Cached EVIO files are located at /cache/halla/sbs/raw
To write files from tape to cache see documentation here, https://scicomp.jlab.org/docs/node/586
- For example, to get all EVIO splits from run runnumber to cache execute jcache get /mss/halla/sbs/raw/*runnumber*

No output files (logs or ROOT) should be stored in the work directory
They should be stored in the "volatile" directory
- Go to /volatile/halla/sbs
- Created a directory here with mkdir username
