sPHENIX discussion of software

[pinkenburg <pinkenburg AT bnl.gov>]

    Hi Evgeny,
    
    in our tutorials is a simple perl script which will generated a
    generic subsysreco module with just couts in all available methods
    including autogen.sh, configure.ac and Makefile.am:
    
https://github.com/sPHENIX-Collaboration/tutorials/tree/master/CreateSubsysRecoModule
    
    That should give you a good start with a functioning build
    environment. In my pre workfest tutorial under
    https://indico.bnl.gov/event/7254/ on slide 24 is a picture how this
    plays together. We have a similar script if you want to have a
    template for a new G4 detector:
    
https://github.com/sPHENIX-Collaboration/g4exampledetector/tree/master/template

We have quite a few examples which go over various containers (hits, cells, towers) and dump the content into ntuples:
https://github.com/sPHENIX-Collaboration/coresoftware/tree/master/simulation/g4simulation/g4histos

you can cut and paste the loops from there

Dear All,

I have a question.
I am quite new to the sPHENIX SW structure.

And I want to write a simple compilable C++ code to read GEANT4 simulation files. It needs these includes:
#include <g4main/PHG4HitContainer.h>
#include <g4main/PHG4Hit.h> 

and load: 

gSystem->Load("libg4testbench.so"); gSystem->Load("libphg4hit.so"); 

How can I do it?
I am doing all the code on rcas2062.

I have looked through the following links:
https://github.com/sPHENIX-Collaboration/analysis/tree/master/SimpleTrackingAnalysis
https://github.com/sPHENIX-Collaboration/analysis/tree/master/Ana

I understand now that I need to use automake infrastructure, which is completely new for me.

Is there a tutorial on how to write an analysis code from scratch in the sPHENIX environment on something simple?

For example, reading hits from Geant4 files (which I am trying to do)?

The idea is to use compiled code, not root/CINT scripting.

Cheers,
Evgeny

Hi All,

We will meet to discuss tracking software tomorrow, Wednesday August 5, at 10:30 am ET. The agenda page is at:

https://indico.bnl.gov/event/9107/

The Blujeans connection is:

https://bluejeans.com/553808487/

I will show some slides on track matching to the silicon detectors. We should also have a discussion about how we will integrate track seeding, vertexing, and track fitting as we move forward.

Best regards
Tony
