Root ntuples to hbook

Dear all
Is there any way to convert root tree to hbook ntuple ?
with best regards , Alexey

It is not possible to convert a general ROOT TTree to hbook in general.
Some people have written applications to convert simple ROOT ntuples to hbook. See for example:
www-numi.fnal.gov/offline_softwa … ode17.html
www-hera-b.desy.de/subgroup/slowctrl/HbDisplay2/

In case of problems contact the original authors, not this list.
