DQ2Client quick usage

Introduction

This page aims to help ATLAS users to quickly browse, search, retrieve ATLAS datasets for analysis. The page is organized by several use cases.

Setup environment

% source /project/atlas/nikhef/dq2/dq2_setup.(c)sh.NIKHEF
% voms-proxy-init -voms atlas

List datasets

The following command lists the merged FDRII AOD datasets of the Muon stream.

% dq2-ls fdr08_run2*Muon*merge*AOD*
...
