Hi Rooters,
I am new with Root and maybe this is a naive question:
Can i store objects containing a TClonesArray into another
TClonesArray.
I have tried to do that and put the information in Tree with
split=1 and write it to a file. When i try to read the file the
ClonesArrays aren't recovered.
After i changed my TClonesArray to TList and everything was Ok.
Thanks in advance, Manuel.
