Key Points

Introduction	Finding the data is non-trivial, but all the information is on the portal 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 sometimes inspect the files before diving into the full analysis Some files may not have the information you’re looking for
Hands-on activity	The information is all there for you to find datasets you want for your analysis. But it make take some poking around to find it. Familiarizing yourself with the search options is time well-spent.
