Hi, I want to use a class generated by MakeClass to loop over a tree and a friend. I have found some information about this at: http://root.cern.ch/root/roottalk/roottalk01/1749.html Unfortunately this seems to work only if the friend has the same structure as the original tree. Is there a trick to make it work when variables in the friend do not exist in the original tree? In other words can I get the same flexibility with MakeClass as with Draw, ie that variables in the friend seem to be in the original file? Thanks, /Yann +------------------------------------------------------------------+ | Yann Coadou Fermilab MS 357, PO Box 500, Batavia IL 60510, USA | | phone: +1.630.840 5400 fax: +1.630.840 6650 email: yann@fnal.gov | +- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - + | Uppsala University Department of Radiation Sciences (ISV) | | PO Box 535, 751 21 Uppsala, Sweden Phone: +46.18.471 58 27 | +------------------------------------------------------------------+
