Unable to add an event block to a reaction rate in SimBiology

1 view (last 30 days)
I'm unable to add an event block to a reaction rate block (ke) in SimBiology diagram view (taken from the help page "Model Views in SimBiology App") - please see attached file. When I connect the two blocks the event block for the reaction rate block is still undefined.

Hi Jacopo,
The parameter you are adding the event function to, ke, is currently "reaction-scoped". If you change the scope of your parameter ke to be "model-scoped" you will be able to add the event function to ke. Note that you will have to change your EventFunction to from reaction2.ke = ... to ke = ....
This behavior is rooted in SBML standards but it would be helpful for us to understand why you want ke to be reaction-scped as opposed to model-scoped. Is there a particular reason why you want ke to be reaction-scoped?
Let me know if that helps.
Best,
Sietse

Hi Sietse,
I'm new to SimBiology and I was just following the help page "Model Views in SimBiology App"; I might have done something incorrectly while following the tutorial but can't figure out what.
How do I add a reaction rate that is model-scoped instead of reaction-scoped? I think that what I was doing was to specify ke when I was creating the reaction. Is this a wrong way of specifing parameters?
Many thanks,
Jacopo

If you right-click on the parameter in the browser, you can 'Change Scope', see the screenshot betlow.
