• dq2-get -f DBRelease-10.3.1.tar.gz ddo.000001.Atlas.Ideal.DBRelease.v100301

Then, to process all events in a simulated-data file, run a command like this:

• processAOD_trf.py AOD.129495._000001.pool.root.1 True ntuple.root 0 DBRelease-10.3.1.tar.gz -1

To process all events in a recorded-data file, run a command like this:

• processAOD_trf.py AOD.pool.root False ntuple.root 0 NONE -1

How to submit jobs to the Grid

In the scripts directory, there are two files for submitting Grid jobs using pathena: submitAODRec.sh and submitAODSim.sh. The general configuration is at the top; the commands to run on specific datasets can be added at the bottom. The N_FILES_TO_MERGE setting at the top refers to the number of files that can be merged into a single file later on; see below. This merging can be useful because running jobs on the Grid may produce many output files; however, merging them all into a single file at the end may not be possible if the resulting file would be too large.

output files from the Grid

If you submitted the Grid jobs using the scripts above, then the file download_recorded.sh }} or {{download_simulated.sh should have been produced. Edit the scripts/downloadDS.sh to configure the download parameters, then run the download_recorded.sh }} or {{download_simulated.sh script to download and merge the output files.
