Creating a Dataset

• Sam create dataset definition
• --defnamemcbot3
• --groupcdf
• --defdescbottom mc
• --dimfacilityname cdf-fzkka and groupname cdf
  and run number 150110 and appname pythia and
  appversion 6.203
• The hard part anticipating how users can get
  unique results when they make a dataset!
• This then goes into the datasetmcbot3 in your
  DHInput.

14
Recommendation

• Each of the 5 physics group MC producers give
  thought to how data are to be accessed and
  develop a policy
• Start with Saverio and B group to try this out
  and see how we want to specify the data
