Hello,
ROOT leaves without saying anything when I try to write a TTree in a
TFile, and the file has only few bytes (and can not be opened of
course).
I have a global tree: TTree TREE("T","TREE");
In a function, I fill it, then:
TFile *myfile=new TFile(name_ntuple, "RECREATE");
TREE.Write();
myfile->Close();
This is the way I always used, and it always worked, but this time I
have a big Tree and this doesn't work, I don't know why.
Its size is less than the limit 2Gb, I think it should be around 80Mb
with 100.000 entries (I have already a similar file of 8Mb with 10.000
entries that I succeeded to write).
Have you an idea of what goes wrong ?
Thank you.
