  • A careful understanding of the search options can help with finding what you need

Where are the datasets?


  • Use the filter selections in the left-hand sidebar of the CERN Open Data Portal to find datasets.

What data and Monte Carlo are available?


  • The collision data are directed to different datasets based on trigger decisions.
  • The Monte Carlo datasets contain a specific simulated physics process.

How to access metadata on the command line?


  • cernopendata-client is a command-line tool to download dataset files and metadata from the CERN Open Data portal.

What is in the datafiles?


  • It’s useful to inspect the files before diving into the full analysis.
  • Some files may not have the information you’re looking for.
