Slow LxPlus TBrowser


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.

Thank you!


Maybe this post can help: How to copy one file's content into a new file's directory?
And BTW, I would suggest to copy the file locally, as sometimes lxplus is quite slow…

Cheers, Bertrand.

Thank you! I copied the files locally and this is much better.
