Hello,
I have a question about handling root files.
Is there an easy way to split a root file containing branches into to two files each containing half of the events of the original file ( obviously if the number of events (n) is odd then one file would contain abs(n/2) and the other file would contain abs(n/2)+1 events)
By easy way I mean a way without writing a code that opens the original root file, reads the events and then creates 2 root files. What I have in mind (if this helps) is the reverse think of the command hadd.
I am asking because I have a large root file that my laptop cannot handle. I also think that this would help people that copy/transfer large root files from remote computing centres.
Thanks a lot!
