Network diagrams are dynamically arranged into a forced-layout. Node positions can be changed by clicking and dragging a node. Upon initialization, only species nodes, metabolites and reactions nodes are rendered. To access internal metabolites and reactions, click the enter button which hovers over species nodes. Panning and zooming of the network is also supported by using the mouse wheel or trackpad.
To create a network, choose a set of species from the drop down menu by pressing the choose species button. The community metabolic network will subsequently render automatically if you select more than one specie
To add metabolites or reactions, use the navigation bar, the button shaped like a pencil from the above image. One selected you are given the ability to add, remove metabolites and reactions to your current specie
To perform flux balance analysis on the model, press the optimize button and wait for calculations to finish.
