Re: Warning - not a TStreamerInfo object

Hi,

This usually happens when you are reading a file created by a newer version of ROOT (v5.27 or above) using an older version of ROOT (v5.26 or older). There is patch version of some of the older version of ROOT that have been update to suppress correctly this message (for example v5.26/00c and above).

Cheers,
Philippe.
