  • Do NOT copy/store ROOT files in $HOME/*. Filling $HOME on the adaq cluster and other JLab machines will cause major problems for you and others. Besides, we have much more space on the work disk (see below).
  • Do NOT copy/store data files to $HOME/* for any reason.
 If you need to create customized ROOT files then please make a personal directory here:
 and direct the analyzer to use that path.

Retrieving files from the Silo/Auger

Use jcache to retrieve files from tape. They will show up in '/cache/mss/halla/e06014/raw/' in a few minutes (usually). The analyzer will automatically find them there.

For example: jcache /mss/halla/e06014/raw/e06014_1246.dat.0 puts the file in '/cache/mss/halla/e06014/raw/e06014_1246.dat.0'

 There are very few good reasons to need to copy/store root files or data files in your home directory.  
 Please leave the data files on the /cache/* disks and keep root files on the /work/halla/e06014/* file system.

A backup of all files in /adaqfs/home/adaq/e06014/ (online replay files, etc) was made on 01 Sept 2009. (This is in addition to JLab's standard backup mechanisms.)

  • It can be found at /work/halla/d2n/adaq-e06014/ (read-only).
  • A tarball (1.6 GB) can be retrieved from the Silo to your current working directory with this command. (As a rule, you should not have to do this.)
 jget /mss/home/brads/e06014_adaq_directory-01Sept09.tar .

  Off Line Analysis for transversity
  A how-to on using JLab's computer farm to analyze Hall A data.  This page uses Transversity's
  paths, run numbers, etc. Be sure to use the d2n work disk for output!

Online Replay for Experts

(Some useful examples here but they use the Transversity configuration. Adapt accordingly.)

Offline Replay Instructions

Calendar, Run Periods

  • "Run Calendar"
    • It comes up with todays date by default. You want to move back to Feb. 2009 and Mar. 2009. Snapshots are below.
