_ROOT Version: 6.26/10
_Platform: Ubuntu 20.04.5 LTS
I am trying to open a file using root, when i open it using TBrowser, it gives the following warning/error
but allows me access to the plots.
however when i use the following command in terminal using root
root  std::unique_ptr myFile( TFile::Open(“pain.root”));
Error in TKey::ReadObjWithBuffer: Unknown class $� *�!!
Info in TFile::GetStreamerInfoList: cannot find the StreamerInfo record in file pain.root
root  myFile
(std::unique_ptr &) std::unique_ptr → nullptr
i am left with a null pointer
Since TBrowser Can access the file, there must be someway for me to access.
The file has many trees and i want to write a small script to make it easy for me to get some particular plots.
P.S. Sorry for any lack of information, i am new to this software and community.
