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:

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):
- 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)
- nsls -l /castor/cern.ch/user/b/balagura/siw_ecal/sps_tb_2015/
this lists all files in the directory (equivalent to ls -l)
- 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
- tar xvfz <your_local_file.tgz>
this extracts all files from the tarball
