Adaption of a run 2 analysis to the O2 framework for run 3

For run 3 of the LHC a new data structure and analysis framework (O2) for ALICE is being developed. During this development, existing physics analyses have to be transformed accordingly. To assess the issues of such a conversion, an existing analysis was recreated within this project. First some run 2 data was transferred into the run 3 data structure. After this the analysis steps were also transferred to the new framework. It was shown that it is possible to convert an existing analysis into the prototype of the O2 analysis framework.
