I am facing a problem when trying to build a new index on a TChain.
I have some files with a TTree, where an indexing is already built. When creating a TChain out of these files and trying to make a new index I get the following error:
Error in <TChainIndex::TChainIndex>: Tree in file test.root has an index built with majorname=a and minorname=b Error in <TTreePlayer::BuildIndex>: Creating a TChainIndex unsuccessful - switching to TTreeIndex
Is there something I am missing?
Thanks for your help.
