This function creates an empty undirected graph with vertex count equal to
the atlas specified, and includes some graph-, vertex-, and
edge-level attributes that are important for brainGraph functions.
Basically a wrapper for make_empty_graph.
make_empty_brainGraph(atlas, ...)Character string of the atlas to create a graph from
Other arguments passed to make_brainGraph
An empty brainGraph graph object
Other Graph creation functions: make_brainGraph,
make_ego_brainGraph,
