To run the notebook for this post in version 12.0 of Mathematica make the following changes:

1) Replace the first input

<<CompartmentalModeling`

with

Get@CloudObject["https://www.wolframcloud.com/obj/rnachbar/Published/CompartmentalModeling.wl"]

2) Replace all instances of stochasticSolve with StochasticSolve

3) Don't evaluate the input in the section "Simulation loop"

Thank you for your help.

The stochastic simulation is not running properly because it's trying to use the CreateDataStructure function which is not in version 12.0.

Let me see what it takes to run the notebook in version 12.0, and then send you either a short list of changes, or a new notebook. I might not be able to get to this until Wednesday, however.

First I 'd like to thank you for you kind reply. Really I have version 12. How can I fix the problem in version 12 ?

What version of Mathematica are you using?

Version 12.1 or newer is required to use the new built-in data structures that are used by the stochastic simulation code (for example, CreateDataStructure).
