  • 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.

d2n Analysis To Do List

d2n-analysis mailing list

Subscribe by sending an email to the address
with the command 
   subscribe d2n-analysis
in the email body.  The subject is ignored.  You should receive an "approved" email
within a few minutes if it worked.

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 '/cache/mss/halla/e06014/raw/e06014_2609.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 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!
