Dataset access

LCD-WG datasets are accessed through Dirac, as explained in:

• https://twiki.cern.ch/twiki/bin/view/CLIC/DiracUsage

Quick start

source /afs/cern.ch/eng/clic/software/DIRAC/bashrc
dirac-proxy-init

Registration

Before first use, register in ILC VO, and email grid certificate DN to ilcdirac-register@cern.ch asking to be added to ilcdirac.

Not clear whether special credentials are needed. If so: in ~/.glite/vomses add:

"ilc" "grid-voms.desy.de" "15110" "/C=DE/O=GermanGrid/OU=DESY/CN=host/grid-voms.desy.de" "ilc" "24"

File access

To see what's in there, do:

dirac-dms-filecatalog-cli
ls /ilc/prod/clic/

To get a file:

dirac-dms-get-file /ilc/prod/clic/500gev/ZZ/ILD/DST/00000443/000/ZZ_dst_443_90.slcio

There is a datasets directory on AFS in /afs/phas.gla.ac.uk/data/ilc/datasets01/ and there is a simple script, /afs/phas.gla.ac.uk/data/ilc/datasets01/get_clic_files.sh, that one can use to download the files listed in the SignalDatasets1 wiki.

Data Catalogues

Online data catalogues:

• ILD MC Production Database: https://ilcproddb.desy.de/admin/ild/gen/
• Simulations DB: http://www-flc.desy.de/simulation/databasesimulation/

To understand the labelling of the dataset directories, the WHIZARD nomenclature might prove useful.
