pafway                  Find pairwise-associations between annotations
                        in a network without edge weights.
pafway_edge_weights     Find pairwise-associations between annotations
                        in a network with edge weights.
pafway_meta             Compare the frequency of observed edges of a
                        specific type and the expected frequency of
                        these edges, given the presence of a different
                        edge type
