But $tree is not a GeneTreeNode object, it is a GeneTree object in my case:
my $tree_adaptor = $reg->get_adaptor('Multi', 'compara', 'GeneTree');
my $tree         = $tree_adaptor->fetch_by_root_id(487410);


Bio::EnsEMBL::Compara::GeneTree=HASH(0x2a85b40) does not understand 
method Bio::EnsEMBL::Compara::GeneTree::children



In the documentation I only see root method that returns a GeneTreeNode 
object from a GeneTree object.
