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
% dq2-ls -r fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10 INCOMPLETE: RAL-LCG2_DATADISK COMPLETE: PRAGUELCG2_DATADISK GOEGRID_DATADISK TRIUMF-LCG2_DATADISK ... NIKHEF-ELPROD_DATADISK ...
List dataset files
The following command lists the files in a particular dataset
% dq2-ls -l fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10 fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10 [X] fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10._0004.1 9C32CDB7-7638-DD11-8B46-0030487C782A ad:6906bd22 3044690419 [X] fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10._0007.1 8AEBE6D3-7638-DD11-A9B9-0030487CD836 ad:72aacdf0 3013049170 [X] fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10._0002.1 96E34CB5-7638-DD11-B584-0019DB29C602 ad:be45ed57 2990039386 [ ] fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10._0003.1 5C4857B2-7638-DD11-87BB-0030487CD762 ad:19ebf510 2991127754 [X] fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10._0009.1 5E0F0BCC-7638-DD11-B69A-0030487CD938 ad:e96929bb 2008226831 [ ] fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10._0005.1 526C74BC-7638-DD11-9959-0030487CD16C ad:72859987 2994945608 ...
The meaning of each column:
| column # | example | meaning |
|---|---|---|
| 1 | [X] or [ ] | existence of the file in local site. Cross means it exists. |
| 2 | fdr08_run2.0052293.physics_Muon.merge.AOD.o3_f8_m10._0004.1 | The logical file name |
| 3 | 9C32CDB7-7638-DD11-8B46-0030487C782A | the Global Unique Identifier (GUID) |
| 4 | ad:6906bd22 | the checksum |
| 5 | 3044690419 | the file size in byte |
