[ROOT] Question concerning AddFriend() member function and subdirectories

Hello,

I've been using the AddFriend() feature extensively recently and found it 
very useful. The feature works fine for trees located in the main directory 
of a file. The problem I have concerns adding friend trees from 
subdirectories e.g.

TTree *t=new TTree();
t->SetName("mparam_tree");
t->AddFriend("v25 = valid_inc25","IEM.root:/IEM_rnd");
t->AddFriend("v45 = valid_inc45","IEM.root:/IEM_rnd");

for trees "valid_inc25" and "valid_inc45" in ROOT file "IEM.root" and 
subdirectory "IEM.rnd".
I've tried all variants for the file description, with or without : or / 
etc....

Is there something I'm doing wrong or has this feature not been added yet ?

Regards

Malcolm
