Where to connect a ModificationLink

The connecting points on the BaseLink are a process node.

ReactionLink = BaseLink + ReactantLink + ProductLink + ModificationLink

When a ModificationLink is added, in respect to the logic structure of a model, there is no increase or decrease in the number of Reaction(s). The ModificationLink is connected to the BaseLink and becomes a part of the Reaction.

To check which Modifiers are added to a Reaction

1. In the List Area, click Reactions tab.
