Getting the raw data files from the repository

  • raw files are permenantly stored in /cache/mss/halla/gmp12/raw/
  • to draw a data file from the repo, login to the farm
 ssh username@ifarm

and then ask for the file

 jcache submit default /mss/halla/gmp12/raw/gmp_20314.dat.0 
 > Your request is submitted. Use id '4678425' to check the status

this procedure may take a few minutes

  • raw files will be now stored for several days in /cache/mss/halla/gmp12/raw/

 .x replay_L.C(run_number)   (provide run_number you want to replay, for left arm it is < 20000)
  • answer any questions, if needed
  • exit analyzer by doing
 .q
  • For RHRS, at the terminal, use
 .x replay_R.C(run_number)   (for right arm it is >= 20000)
