h1. How to Reach the SBS Work Directory

* Log in to the JLab ifarm

** https://scicomp.jlab.org/docs/getting_started

* 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.

h1. Setting up Environments

* If you want to set up your own personal analyzer you can look here https://github.com/JeffersonLab/analyzer

h1. Getting Files from Cache

* All raw EVIO files from GMn are on tape at @/mss/halla/sbs@

* Cached EVIO files are located at @/cache/halla/sbs@

* 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 in GMn to cache execute @jcache get /mss/halla/sbs/raw/*runnumber*@

h1. Setting up the SBS Replay

* 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 make your own changes to the analysis
