Hi @Annzm,

Thanks for the report. I am adding @silverweed and @pcanal in the loop who might have ideas on what might be going wrong.

Cheers,
Dev

This problem has been solved in recent version/patch release of ROOT. Which version are you using to run hadd? Which version was used to produce the files?

Annzm · August 25, 2025, 12:49pm

thanks for responce.
actually im using hadd with ROOT 6.28/04(LCG_104) to merge skimmed files which were orignally processed from DAS (NANOAOD) produced with CMSSW_13_0_13. For skimming i also used ROOT 6.28/04(LCG_104).

To solve the problem, you would need to use CMSSW_13_3_3 when writing
or when reading you would need to use v6.28/06 or later.
