Friend trees of "filtered Trees"

Hi, All,

I was wondering how easy it is for a TTree to access a "friend" TTree when the events of the first tree are a subset of the second? The application would be where the user filters events from one TTree and drops some branches, but then wants to access the original for debugging purposes.

I've only used friend trees when there is an event-by-event match. Is this functionality possible directly with friend TTrees?

Thanks,
