I am just trying to run a root macro while using a ".._pid.root" and "".._par.root" data which were created with a linux ubuntu based server via "pandaroot-dev" version. That is, i am trying to run this macro on my PC, a Mac which runs "pandaroot-oct19" version and i get this error below. Any help will be appreciated. Thank you.
Error in <TFile::ReadKeys>: reading illegal key, exiting after 1 keys
Warning in <TStreamerInfo::BuildCheck>:
The StreamerInfo of class PndEvtGenDirect read from file signal_pp_Zc4430Minus_ee_nophot100000_1_par.root
has the same version (=1) as the active class but a different checksum.
You should update the version to ClassDef(PndEvtGenDirect,2).
Do not try to write objects with the current class definition,
the files will not be readable.
