Note: Artistoo was formerly called CPMjs.
You can find full documentation of available methods here, or have a look at the manual for tutorials to get started. Alternatively, see below for a brief description and a list of examples.
This code has been ported over from our older "cpm" repository. This is now an ES6 module,
which is compiled trough "rollup" for use in the browser. Users who wish to use this version
of Artistoo can use the compiled code in the build/ folder as it is; there is no
need to compile anything. See below for examples and how to use them.
Developers can extend the code with their own modules; documentation will follow later (see the Makefile).
Artistoo can be used to create interactive simulations in the webbrowser. We have implemented several examples showing various processes that can be simulated with a CPM; see the links below. (Please note that these examples may not work properly in Internet Explorer).
We have the following examples for web-browser CPMs (see also examples/html):
- A simple Ising model
- A simple 2D CPM cell
- The classic CPM cell sorting example
- Dividing CPM cells
- A cell moving through active cell migration
- Migrating cell in a microchannel
- Migrating cells on adhesive patterns
- Simulating plain diffusion
- Cells moving up a chemokine gradient
- Multiple cells migrating together, interactive web page
- Cells moving towards a target point
- Cells moving in the same global direction
- A layer of tightly packed epidermal cells
- T cells moving in the epidermis
- Cells producing a chemokine with other cells responding to it
- Cells moving with a preferred direction
- Particle following a random walk
- T cells invading a growing tumor
- An example of how to deal with non-periodic grid boundaries
We also have a few examples of plain cellular automata (CAs):
Simulations can also be run from the command line using nodejs. The first time you do this, you have to install several dependencies. Go to the base folder of this package and run
npm install
which will automatically install the dependencies as supplied in the package.json file.
Here's an example of how to run the node script:
cd examples/node
node run-ActModel.js
This may give an error the first time, because the script is trying to store images of
the simulation to a file output/img/ActModel which does not exist. Create this directory
and try again:
mkdir -p output/img/ActModel
node run-ActModel.js
This will print some output to the console; typically the centroid of each cell at each timepoint. See the node script and the Simulation class for details.
To create a movie, run:
mkdir -p output/mp4
ffmpeg -r 60 -f image2 -i output/img/ActModel/ActModel-t%d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p output/mp4/ActModel.mp4
