Sometimes one has many files that are supposed to contain the tree one is interested in but, due for example to a tight selection, some may not contain the tree. It is nice however to be able go blindly give the list of files without worrying which ones contain the tree and which ones do not.
If the file with the missing tree is not the first one that can be achieved in read_root by the option warn_missing_tree=True that is passed to root_numpy.root2array. Instead, if the first file miss the tree there is an error because of https://github.com/scikit-hep/root_pandas/blob/master/root_pandas/readwrite.py#L163 (seed_path = paths[0])
