Filling Branch with array of float + 1

ROOT
1

Good morning,

I’m want to create a tree with 3 branch.
I have a problem with the third branch. I want to fill this branch with an array of float but with a size equal to GROUPES + 1.

The code is in this moment :

 	TTree * tDecoupages = new TTree("DECOUPAGES","DECOUPAGES");
  		tDecoupages->Branch("NOM_DEC",dec.nomdecoupage,"NOM_DEC[64]/C");
  		tDecoupages->Branch("GROUPES",&dec.groupes,"GROUPES/I");
  		tDecoupages->Branch("BORNES",dec.bornes,"BORNES[GROUPES]/F");

But I want a thing like this

  		tDecoupages->Branch("BORNES",dec.bornes,"BORNES[GROUPES+1]/F");

How can I do this ?

Thx for your help

[quote]But I want a thing like this [/quote]This is not supported, you will need to add another variable that contains the value of GROUPES+1.
