Issue with Missing AliAnalysisTaskSE.h When Running Local ALICE Analysis

Hello everyone,

I’ve been working on setting up a local analysis using O2Physics on my computer. I have spent quite some time modifying my analysis script to process my own dataset following the steps outlined in the ALICE analysis tutorial (Running locally · ALICE Analysis Tutorial).

However, when I try to run my analysis, I encounter the following issue:

Fatal error: 'AliAnalysisTaskSE.h' file not found

I have structured my script to load AliAnalysisTaskSE.h , but it seems that my system cannot find this class. I expected it to be available within the ALICE framework, but I’m unsure if I need to install an additional package or configure my environment differently.

I would appreciate any guidance on how to properly include AliAnalysisTaskSE.h or resolve this missing class issue. Has anyone else encountered a similar problem while running local analyses with O2Physics?

I have worked hours on this any help or suggestions would be greatly appreciated!

Thanks in advance!
