Quick Tour of the epic and eicrecon repositories

Overview

Questions

• Where does some relevant code live, and what does it look like?

Objectives

• Explore a few key repositories.

A deep, interactive dive into either package would exceed the time frame of this tutorial. Some of it will be covered in the following tutorials. While build times, especially for eicrecon on a Silicon Mac are somewhat prohibitive, you know now how to do it. For any interactive work later today, it is strongly recommended to use eic-shell either on an intel machine, or at least start the build right now. Note that only the initial build will take that long, changes to a few files generally don’t trigger the rebuild of an entire package.

Detector geometry is handled by the epic package. Sub-detector cml filese are in epic/compact, their corresponding C++ (Geant4) implementations in epic/src

Configurations (like bruycecanyon, craterlake, customized ones for special purposes are in the epic top level directory, but instead of making changes here, add to or edit the YAML files in epic/configurations, rebuilding the package will auto-generate the composite configurations.

Key Points

• The [epic repository])(https://github.com/eic/epic) contains the detector geometry descriptions. The eicrecon repository handles digitization, reconstruction, and pre-analysis such as jet-finding.
