TDSet::AddFriend

ROOT

Hi,
TDSet::AddFriend allows me to add a friend tree to a TDSet. As far as I understand, PROOF splits jobs per input files (i.e. entries in the main TDSet) - even though I can’t pin that down looking at the doc. I’d like to add a TDSet-friend consisting of a single TTree to a TDSet-TChain (where of course the single TTree-friend has as many entries as the TChain). Does that make sense in the context of PROOF?
Axel.

Hi Axel,

it makes sense but is alas not yet implemented. Will be coming in the very near future.

Cheers, Fons.

Has this feature been added yet (its now 2010)? I haven’t been able to find any new information about it.

thanks!
