Hi!

edmDumpEventContent is a CMSSW helper script and it expects the input file to be in the CMS EDM (Event Data Model) format, see WorkBookCMSSWFramework < CMSPublic < TWiki

That would be an AOD or a MiniAOD file. If your input is a plain root file, have a look at ROOT files - ROOT

Hope this helps.

Best, Kati
