-To convert root files to LHCO files a standard tool does not exist, because it depends on the structure of the user root file. A root/lhco converter script to convert tH analysis root ntuples in lhco file is going to be implemented and it will be posted here as soon as it will be ready.+__**ROOT to LHCO**__: To convert root files to LHCO files a standard tool does not exist, because it depends on the structure of the user root file.
