Ntuple Structure:

Data Storage


  • The storage h/w is pcdream:/mnt/storage
    • It is a 3 TB external disk connected to pcdreamdaq2
  • The storage element at TTU
    • Used to mirror, via GlobusOnline, the pcdream:/mnt/storage/ disk
    • ~Daily TTU mirror procedure:
      • Login to
      • Execute: scp -r -s 0 -v PCDREAM:/mnt/storage/ TTU-Sigmorgh-DREAM:/lustre/hep/osg/dream/2014/
    • The script ~/bin/ttuls from the dreamtest directory on pcdreamdaq2 lists files hosted in the storage element at TTU. E.g.: ~/bin/ttuls data but REQUIRES the TTU endpoint to be activated by Michele, Sehwook or Alan to work
    • How to retrieve data by anyone in DREAM from the storage element at TTU: .see GridHelp / GridSetup / GlobusOnline / DataTransfer pages
  • Where are the data files?

    1. In pcdream:/mnt//storage/
    2. In a disk at TTU. Use the ~/bin/ttuls data script to lists them (How to copy ntuple on your PC)

    Where are the pedestal files?

    1. In pcdream:/mnt/storage/pedestal
    2. In a disk at TTU. Use the ~/bin/ttuls pedestal script to lists them (How to copy ntuple on your PC)

    Where are the ntuple files?

    1. In pcdreamdaq2:/mnt/storage/ntuple
    2. In a disk at TTU. Use the ~/bin/ttuls ntuple script to lists them (How to copy ntuple on your PC)

    [pcdream] /home/dreamtest/working/ntuple >              DRS 32 channels
    [pcdream] /home/dreamtest/working/ntuple/silvia >     DRS read with 16 channels

    Example macros

    A few example macro to analyze the DREAM ntuples.
