Hi all,

I modified the macros so that the TPC drift velocity is automatically set when TpcReadoutInit() is called. In case you get an error in your macro, starting with todays new build , that looks like:
/home/phnxbld/sPHENIX/gcc-12.1.0/new/source/coresoftware/offline/framework/ffamodules/CDBInterface.cc:121: CDB_GLOBALTAG flag needs to be set via rc->set_StringFlag("CDB_GLOBALTAG",<global tag>)

Just make sure that you set the relevant CDB tags before TpcReadoutInit() is called, e.g. as in the updated macro linked below.

https://github.com/sPHENIX-Collaboration/macros/blob/31a1714c5567134379f1f6159febd25fa1859fc6/TrackingProduction/Fun4All_FieldOnAllTrackers.C#L102-L110

Let me know if you have any questions/problems,

Joe
