when trying to run o2-tpcits-match-workflow I get an error from the tpc-track-reader (“Error opening tree”). I tried changing the TrackReader::mTrackTreeName from “tpcrec” to “events”, as this is the name for the tree stored in the tpctracks.root file but then I get a segfault from the accumulate method in the same device.
To be more precise I tried all steps described in the readme of the GlobalTrackingWorkflow and this then fails than at the TPC-ITS matching stage.
Indeed, yes, now it works for me too. When I switched to the cosmics example workflows I forgot that I did not recompile O2 after setting TrackReader::mTrackTreeName back to the default.
When I tried it at first I still had an old list of commands taken from my notes specifying --tpc-track-writer "--treename events". That was my problem.
Sorry for that and thanks a lot for checking!
