Dear ROOT team. First at all - thank you for help on my previous mail. I have Q's about splitting complicated objects to different branches. Let me consider the example : 'track is a collection of hits' ==> class Track : public TList { /* summary info */ } All "hits" are contained in one TClonesArray and "list part of track" - just a pointers to individual hits. Also 'track' has 'summary info' as data fields Q1: how to split : 'hits' --> file1 (trivial) 'list part of track' --> file2 ???? 'summary info' --> file3 ? The second question - 'how to use tape archive ?' We have a some simple implementation of tape archive (perl scripts + mSQL DB) and Q. about 'interfacing' root and existing software. How to ask 'gSystem' to notify me about 'un-existing file' exceptions ? Are there other tips that I need to know ? Or other simple solution (or examples !) exists ??? What is the 'best way' in that case ? Thanks in advance! Nikolay Root BINP, Novosibirsk email : nroot@inp.nsk.su
