Could some please explain to me why am getting the below warning:
Attaching file RandPosition_1_intense.root as _file0…
Info in TFile::Recover: RandPosition_1_intense.root, recovered key TDirectoryFile:RandPosition_1_intense at address 196
Warning in TFile::Init: no StreamerInfo found in RandPosition_1_intense.root therefore preventing schema evolution when reading this file. The file was produced with version 4.00/00 of ROOT.
ROOT Version: 6.28/04 Platform: Ubuntu 22.04 Compiler: c++ 11.3.0
I do not know anything about this macro but indeed something went wrong during its execution. First check the log/print-out when it is/was running. Second re-run it to see if it fails a second time. Thrid run with valgrind --suppressions=$ROOTSYS/etc/valgrind-root.supp to get more information about the kind of failure.
