Does this look a bit like a flux simulator? I haven't got access right now. But from the abstract and the pictures it makes a sound a bit as if. Basically model and simulate the flux of metabolites via connected functions, linear-, step-, etc. It looks a bit like Matlab's SimuLink? Will read tomorrow and amend if necessary.
