TChain

Dear colleagues,

when creating a TChain like this :

TChain mychain("NameOfTheTree");

mychain.Add("myfile1")
...
mychain.Add("myfile1000")

there is an error message when one of the file doesn't contain the required Tree
but it works for the others that contain

==>is there a way to prevent the error message
