How to do a simple parameter scan using Tellurium

A common task in modeling is to see how a parameter influences a model’s dynamics. For example, consider a simple two reaction pathway: -> S1 -> where the first reaction has a fixed input of vo and the second reaction … Continue reading

How to plot a grid of phase plots using Tellurium

Let’s say we have a chemical network model where the species oscillate and you’d like to plot every combination of these on a grid. If so, then this code might be of help.

This code will generate: Here is … Continue reading

Smallest Chemical Reactions Systems that is Bistable

A while back Thomas Wilhelm, published a paper that described the smallest chemical network that could display bistability. The paper that describes this result is: Wilhelm, T. (2009). The smallest chemical reaction system with bistability. BMC systems biology, 3(1), 90. … Continue reading

Smallest Chemical Reaction System with Hopf Bifurcation

A while back Wilhelm, and Heinrich published a paper that described the smallest chemical network that could display a Hopf bifurcation. That is, the chemical species oscillated. The paper that describes this result is: Wilhelm, Thomas, and Reinhart Heinrich. “Smallest … Continue reading

Plotting Bar graph of Species Concentrations in Tellurium

I had a model with 27 flaoting species and I wanted to plot the steady state concentrations on a histogram where the labels were the names of the different species. Here is a general purpose script that will do that: … Continue reading
