DØ software tutorials

A tutorial on the DØ analysis software was held on tuesday 11 February during the collaboration meeting (Wilson Hall, 1 West, from 9:00 until 11:30, and then in the afternoon from 13:30 until 16:00). The following subjects were covered

• DØ framework software analysis              (Reiner Hauser, 9:00-10:30)
• How to do a ROOT based DØ analysis     (Roger Moore, 10:30-10:50)
• Batch jobs on CluedØ and CAB                (Roger Moore, 10:50-11:10)
• dØtools primer                                           (Reiner Hauser, 14:30-15:15)
• SAM tips and tricks                                   (Adam Lyon, 13:30-14:45)
• Play with Monte Carlo                              (Iain Bertram, 14:45-16:00)

The videostream for this meeting is available here. You will need to have RealPlayer installed on your computer to get the videostream. The videostream will remain accessible also in the future.
