I tried to use an user defined TTree indexation in order to merge two TTrre with timestamped data.
One of the two TTree is in fact a TChain with about 500 files and I faced the ordering issue which is
explained in several posts.
I then directly created a TTreeIndex, no complain from ROOT. But when I try to write it into a file, it exits without any error message and the resulting TFile is of course corrupted.
I tried with less files in my TChain : it works.
I assume that the problem is the size of the generated TTreeIndex/TFile but I estimated it to be lower than 1 Go
Any help appreciated.
Regards
Julien
