NOTES:

• 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:
      '/work/halla/e06014/disk1/
 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.

See also: Jasmine Help

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.)
