9 years ago Wasn't SetupProject to be eventually removed completely? Not sure that's something we want to teach to new people...
That aside, SetupProject ROOT has historically been problematic...

9 years ago I've seen a lot of people run into problems when using it. Never used it myself though, always used root through SetupDaVinci or similar.
lb-run ROOT root seems to work fine though!

9 years ago I think lb-run ROOT just defaults to SetupProject ROOT

8 years ago @apuignav is right: we should consider the default to be lb-run ROOT root.
When opening just the default root on lxplus, the following warnings to pop up:
Warning in TStreamerInfo::BuildCheck: The StreamerInfo for version 1 of class TObject read from the file DVntuple_new.root has a different checksum than the previously loaded StreamerInfo. Reading objects of type TObject from the file DVntuple_new.root (and potentially other files) might not work correctly. Most likely the version number of the class was not properly updated [See ClassDef(TObject,1)]. Warning in TStreamerInfo::CompareContent: The following data member of the on-file layout version 1 of class 'TObject' differs from the in-memory layout version 1: unsigned int fUniqueID; // vs UInt_t fUniqueID; // Warning in TStreamerInfo::CompareContent: The following data member of the on-file layout version 1 of class 'TObject' differs from the in-memory layout version 1: unsigned int fBits; //
This is not really a problem but just anoying. This can be changed when using the root version which is compatible with DaVinci, like lb-run DaVinci v36r6 root -l
