3.3.1 Defining a Node
Single clicking on the node in the modelling canvas will highlight the Node Properties Panel fields(Figure 3-3), which are editable. This panel allows you to see and modify the bioentity properties: Name, Aliases, different IDs,etc. In addtion, you can include some biological information e.g. full GO annotations, organism and pathway information; kinetic information: Quantity, Concentration, Unit, Molecular Weight, etc. Apart from that, differnet links lead users to online databases to get more detailed information. Also Full Desciription window which is at the bottom of the panel gives to user full description of the bioentity.3.3.2 Defining a Procces/Reaction
Double click on the Process node in the modelling canvas and a new window, the Process Properties panel(Figure 3-4) will appear. Modify the process properties (process stoichiometry,specify if the process is reversible and other properties) in this panel and. You may also click on the “kinetics” tab to access and modify the reaction/process kinetics.
