sPHENIX tracking discussion

Hi all,

To Tracking experts:

Our current G4_Tracking macro contains:

  bool use_truth_track_seeding = false;    // false for normal track seeding, use true to run with truth track seeding instead  ***** WORKS FOR GENFIT ONLY

Is the "***** WORKS FOR GENFIT ONLY" comment still true ?

From what I could read the PHTruthTrackSeeding is introduced in the tracking chain outside of the use_genfit loop and also replaces all the possible seeders we have (PHTpcTracking, hybrid and CA)

Can someone confirm wether this works for both Genfit and ACTS, or just Genfit ?

As a side note: I think it would make more sense for the seeder selection to use an enumeration, rather than the two existing boolean flags for which only three of the four combinations are valid.

Best,

Hugo
