Re: Names of histograms reset after TFileMerger

I do not understand what you are trying to achieve. Your histograms are correctly merged with the statement
Bool_t result = m.Merge();

but I have no idea of what you want to do with the code following this statement.
Your input files contain a TList of histograms, but you loop on the TKeys as if each histogram was a TKey.
