Description

Using the ALICE analysis framework
ALICE physicists use custom tools that facilitate the analysis of real or simulated ALICE data samples. This example demonstrates the use of the ALICE analysis framework on small samples of both pp and PbPb data taken in the year 2010. The user analysis is represented by a C++ class, which has to implement a few predefined methods to process one interaction event. A template analysis class extracting the inclusive transverse momentum and pseudorapidity spectra of all tracks can be modified to create your own analysis.

How can you use this?

This example requires further reading on the ALICE event data model, which can be found here:

Size: 2.1 MB
Please note that the file you are going to download (PtAnalysis.tgz) is 2086046 bytes big. On an average ADSL connection, it may take long to download it (about less than a minute at 1Mbps).

Moreover, if you use one of the provided Virtual Machines to perform your analyses, then you don't need to download datasets manually, because the VM will fetch all the necessary file chunks via the XRootD protocol.

Manual download of files via HTTP is only necessary if you would prefer not to use the XRootD protocol for one reason or another.

Yes, I understood.
