Hi rooters,

I have many rootfiles (>100) containing TTrees, and also large MultiGraphs.
Is there a simple way to merge only the Trees ?

Thanks

Hi,

If listing all 100 files on a single hadd command is not possible, you might be able to write a script and use TFileMerger or you can simply with in 11 calls to hadd (10 times with the original files 10 by 10 and one last time with all 10 intermediate results).
