Using DQ2 at NIKHEF

Set up

Assuming you have a Grid certificate [1], you need to do the following to be able to use DQ2 at Nikhef:

• setup Grid:
  source /global/ices/lcg/current/etc/profile.d/grid_env.csh
• setup DQ2:
  source setup.csh.NIKHEF

Oh, enneh... don't forget to do a grid-proxy-init.

Tools

• dq2_ls <pattern>
  search for dataset with <pattern>
• dq2_ls -g <dataset>
  lists files in <dataset>
• dq2_get -v -r <dataset>
  get dataset
  with verbose output The option -r is needed to download files 'remotely' via the Grid. As far as I know (correct me if I'm wrong) it is not possible to copy directly from the Nikhef SE (like CASTOR at CERN).
