Data Access

Data files are available:

RAW and Root files at LLR

The data directory containing RAW files and RunSummary is:

  • /data_ilc/flc/ECAL/tb-cern/2015/tb2015/
The root files (1st pass) is on
  • /data_ilc/flc/ECAL/tb-cern/2015/tb2015-pass1/

Root files @ CERN, on EOS:

They are stored on CERNbox https://cernbox.cern.ch which has a direct link to eos (user's space).

Check the OES best practise: https://indico.cern.ch/event/467198/contribution/0/attachments/1199441/1746021/EOS.pdf

The procedure to copy the files is

cd «your data space» (e.g. with sufficient storage, don't use your afs directory... typically a temporary space).
. /afs/cern.ch/project/eos/installation/user/etc/setup.sh
eos ls -l "eos/user/b/boudry/tb2015-pass1/*0086*" (for run0086)
xrdcp --verbose "root://eosuser.cern.ch//eos/user/b/boudry/tb2015-pass1/run_0086_by_dif1.raw.root" ./

Raw, R, ROOT files @ CERN, on CASTOR

Raw files are stored on CASTOR /castor/cern.ch/user/b/balagura/siw_ecal/sps_tb_2015/ as 5 tarballs for run groups: 1-99, 100-199, 200-299, 300-399, 400-end. The last tarball also contains high voltage data. There are also 5 corresponding tarballs for reprocessed (v2) RData (runs_001_099_Rdata_v2.tgz etc.). Root files are in tb2015-pass1.tgz.

The R code, version 2 (v2) used to reprocess raw data -> RData: process_v2.R, presented in https://indico.in2p3.fr/event/12532/contribution/1/material/slides/0.pdf

The procedure to copy the files is (see, eg. http://castorold.web.cern.ch/castorold/ug/node2.html for explanation of CASTOR commands):

  1. export STAGE_HOST=castorpublic
    (for CMS / ATLAS this should be castorcms / castoratlas instead of castorpublic; for csh/tcsh shells the environment is set with
    setenv STAGE_HOST castorpublic)
  2. nsls -l /castor/cern.ch/user/b/balagura/siw_ecal/sps_tb_2015/
    this lists all files in the directory (equivalent to ls -l)
  3. eg. for runs 1-99:
    rfcp /castor/cern.ch/user/b/balagura/siw_ecal/sps_tb_2015/tb2015_runs_001_099.tgz <your_local_file.tgz>

    where <your_local_file.tgz> may be eg. in /tmp/ directory of lxplus

  4. tar xvfz <your_local_file.tgz>
    this extracts all files from the tarball
