MATLAB: Simbiology Error- Invalid assignment syntax or parse error for rule

SimBiologysimulation

I am exercising on the article of Tzafriri et al(2004) titled "Analysis of compartmental models of ligand induced endocytosis" with simbiology. However I am taking the error above according to my rate rules and I don't know how to correct them. Can you please help me? The screenshots of my simbiology project are attached below.

Hi,

When you write a rate rule in SimBiology, you don't write the d/dt on the left-hand side of the equations. For example, the first rate should be

L = (-kf*L*Rs+kr*Cs)*(n/Nav)

Also note the red indicators to the right of the rules. These indicate a problem. If you hover your mouse over the indicator, you might get useful debugging information.

Good luck!

Hi Praveen,

NCA functionality in SimBiology currently doesn't support infusion dosing.

MATLAB: Finding non-constant species in Simbiology Object

What you get is not a function handle but an heterogenous array of SimBiology objects. This array contains a mix of different component types like species, parameters or potentially compartments.

If this is what you want, you can get their names with

names = get(VariableSpecies, 'Name')

But if you only wanted species (not parameters nor compartments), you can get them like this:

speciesObj = sbioselect(modelObj, 'Type', 'Species','Where','Constant','==',false)
names = get(speciesObj, 'Name')
