I am a beginner ROOT user using ROOT In LxPlus.
When I open a large HIST file, TBrowser takes over half an hour to load. I just need to get one folder within this HIST file. Can you suggest how to write a script that opens the large HIST file, gets the ‘MuonPhysics’ folder, and copies its contents to a new file? This way I don’t have to keep opening the entire file in TBrowser, just the folder I am interested in.
