Hi folks,

last week we switched to using the intt survey geometry. The current 
code (and the current default ana.411) is incompatible with the old 
geometry when it is loaded from the cdb which we do for processing data 
(the sims have the geometry stored and are therefore not affected). 
Typically what you'll find in your macro is

  std::string geofile = 
CDBInterface::instance()->getUrl("Tracking_Geometry");

  Fun4AllRunNodeInputManager *ingeo = new 
Fun4AllRunNodeInputManager("GeoIn");
  ingeo->AddFile(geofile);
  se->registerInputManager(ingeo);

I just put the new geometry into the cdb (so running with ana.411 works 
just fine) but now the older ana builds will crash and burn. If you want 
to use an older build (there is no really good reason to do so as far as 
I can tell), you need to set the CDB tag to PROD_ana.410 (data) or 
MDC2_ana.410 (sims) instead of using the default (ProdA_2023 or MDC2) 
via e.g.
  rc->set_StringFlag("CDB_GLOBALTAG","PROD_ana.410");
