Simbiology Desktop Activate Reaction Using Event

I am trying to use an event function in simbiology desktop to activate a reaction that exists in the same component. Is this possible and if so, what is the syntax?

Thanks,

Hi,

Events cannot directly change the Active property. However, you can accomplish the same simulation result by creating an event that changes the value of a parameter. For example, you could set a rate constant to 0 using an event as a way to disable a reaction.

Does that make sense?

Yes, thank you. That answers my question exactly. Just as a quick follow up (I am very new to simbiology), how do I access a rate constant that's part of a reaction? I'm not just sure what the syntax is.

Thank you,

Ah, 2 important details. First, you need to make sure the reaction is scoped to the model. In the desktop, you can right-click to get the option to change the scope. Second, you'll need to uncheck the Constant option. Then, you can change the value using an event.

Perfect, thank you so much. I simply could not figure out how to access the variable. Changing the scope was the key.

Thanks again!
