CRN++: Molecular Programming Language

This project contains implementation of the CRN++ language. CRN++ is a language for programming deterministic (mass-action) chemical kinetics to perform computation. This project contains a compiler, translating CRN++ programs into chemical reactions, as well as simulation framework for simulation of the Chemical Reaction Networks. We rely on the Mathematica package developed by David Soloveichik for the simulation of Chemical Reaction Networks.

Requirements

Mathematica version 11.2 or higher. Earlier versions of Mathematica might be supported, but project was not tested under earlier versions.

Project Structure

Examples of the CRN++ programs are under the examples directory. Each example is divided into two files, mathematica ('.m') file containing the core part of the code (actual program), and notebook ('.nb') file containing the 'glue' code for simulating and plotting the results. User can simply open the notebook file, see simulation results of the program, and update the simulation parameters if desired. The CRN++ compiler and simulation framework are stored in the packages directory.

Writing New Programs

If you would like to develop and test new CRN++ programs, please follow the structure of examples under the examples directory.
