Hi Christof,

I am running the full sim + reco chain, and the clusterhitassoc is present on the node tree.

Tony.

Subject: Re: [Sphenix-tracking-l] Evaluator not matching to truth tracks?

 

Hi Tony, 

another possibility is that the clusterhitassoc container isn't present.

For data reco we dont need it and we can drop it. 

For MC matching we still need to keep it around. 

cheers

Hi Tony,

Argh. This might be a bug introduced by https://github.com/sPHENIX-Collaboration/coresoftware/pull/1484

I had to modify the evaluators to rely on the cluster keys stored in the container and not in the cluster. Doing so, I might have messed up something ...

Not being very familiar to the SvtxEvaluator I could not test it extensively.

If you send me a macro that can reproduce the problem, I can compare between before and after the PR got merged and debug ...

When I run the repository code with updated macros, I see reconstructed tracks and truth tracks in their respective evaluator ntuples, but the matching between them seems to not work. The ntp_track ntuple does not have any truth matching info, and ntp_gtrack does not have any reconstructed track matching info. Do others see this?

Thanks

Tony
