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* ... fdr08_run2.0052280.physics_Muon.merge.AOD.o3_r508_t45 fdr08_run2.0052301.physics_Muon.merge.AOD.o3_r508_t45/ fdr08_run2.0052283.physics_Muon.merge.AOD.o3_r508_t45 fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10 fdr08_run2.0052290.physics_Muon.merge.AOD.o3_f8_m10 fdr08_run2.0052293.physics_Muon.merge.AOD.o3_r508_t45_tid024345 fdr08_run2.0052283.physics_Muon.merge.AOD.o3_r508_t45/ fdr08_run2.0052300.physics_Muon.merge.AOD.o3_f26_m15 ...
The one with "/" at the end indicates a dataset container.
List dataset locations
The following command lists the replica locations of dataset fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10

The meaning of each column:
| header 1 | header 2 | header 3 |
|---|---|---|
| row 1, cell 1 | row 1, cell 2 | row 1, cell 3 |
| row 2, cell 1 | row 2, cell 2 | row 2, cell 3 |
- [X]: existence of the file in local site (defined by $DQ2_LOCAL_SITE_ID). Cross means it exists.
