Re: ROOT file doesn't have any tree though its size is big enough!!!

Hi Genie,

you shouldn't delete the directory that you write the tree into. I cannot tell whether that solves it because your macro takes too long for my patience. If not deleting teh directory doesn't solve it: can you come up with a much much much faster version that shows the same behavior?

Cheers, Axel.
