Weights for different score functions of a story

(a) Enzyme activation first			(b) Concentration Change first			(c) Enzyme inhibition first
Outgoing arcs			Outgoing arcs			Outgoing arcs
Arc	To red	To green	Arc	To red	To green	Arc	To red	To green
From red	0	1	From red	1	−1	From red	0	−1
From green	−1	0	From green	−1	1	From green	1	0

Note: Table exhibiting the arc weights for interactions between green and red nodes used for computing the score of a story in the context of a metabolomics experiment: (a) weights used to privilege enzyme activation, (b) weights used to privilege concentration change and (c) weights used to privilege enzyme inhibition.
