How to split subdirectories into different root files?

Hello,

I have a root file which contains 5 subdirectories. Each subdirectory also consist of few directories and many histograms are in each directory.

I want to make each directory into a separate root file, of course subdirectories should belong to the top directory.

Does this kind of class exist already somewhere?

Regards,

Hi @dongjokim,
and welcome to the ROOT forum!

I don’t think we have helper functions or helper structs for something like that. The command-line tool rootcp might be what you need: rootcp 'source.root:subdir/*' dest.root should work.

Cheers,

thanks for your answer and suggestion. I might try to make a script to do the job with rootcp since I have 2 or 3 subdirectories.

Cheers,
