# crnsimulator Simulate Chemical Recation Networks (CRNs) using Ordinary Differential Equations (ODEs).

You have to set initial species concentrations, and choose an output-format, e.g.: ```sh ~$ python ./ozzy.py --p0 A=0.1 B=1e-2 C=1e-3 --t8 10000 --pyplot ozzy.pdf ``` This example plots a simulation on a linear-time scale (0 - 10000) to the file `ozzy.pdf` . ### Tips and Tricks: You can pass the command line options for ozzy.py directly to `crnsimulator`. This will automatically simulate your ODE system. Use --force to overwrite an existing `ozzy.py` script. ```sh ~$ crnsimulator --p0 A=0.1 B=1e-2 C=1e-3 --t8 10000 -o ozzy --pyplot ozzy.pdf < oscillator.crn ``` You can specify the CRN in a single line: ```sh ~$ echo "A+B->2B [k=0.2]; B+C->2C [k=0.4]; C+A->2A" | crnsimulator --p0 A=0.1 B=1e-2 C=1e-3 --t8 10000 -o ozzy --pyplot ozzy.pdf ``` You can specify default initial concentrations of species: ```sh ~$ echo "A @i 0.1; B @i 1e-2; A+B->2B [k=0.2]; B+C->2C [k=0.4]; C+A->2A" | crnsimulator --p0 C=1e-3 --t8 10000 -o ozzy --pyplot ozzy.pdf ``` If you can set which species appear in the legend using --pyplot-lables. If you are writing a new executable (you may need --force), then you can also control the order: ```sh ~$ echo "A @i 0.1; B @i 1e-2; A+B->2B [k=0.2]; B+C->2C [k=0.4]; C+A->2A" | crnsimulator --p0 C=1e-3 --t8 10000 -o ozzy --pyplot ozzy.pdf --force --pyplot-labels C B ``` ### Using the `crnsimulator` library: The easiest way to get started is by looking at the crnsimulator script itself. However, here is a small example using the above oscillating CRN. ```py >>> from crnsimulator import ReactionGraph >>> crn = [[['A', 'B'],['B','B'],0.2], [['B', 'C'],['C','C'],0.8], [['C', 'A'],['A','A'],0.9]] >>> RG = ReactionGraph(crn) >>> svars = ['B', 'C', 'A'] # let's enforce the order of species, because we can! >>> filename, odename = RG.write_ODE_lib(filename='ozzy.py', sorted_vars = svars) >>> print('Wrote ODE system file:', filename) Wrote ODE system file: ozzy.py ``` Then go ahead and execute `ozzy.py`: ```sh ~$ python ./ozzy.py --p0 1=1e-6 2=2e-6 3=5e-6 --t8 1e8 --pyplot ozzy.pdf --atol 1e-10 --rtol 1e-10 ``` ... or load its functions by treating it as a python library: ```py # Import >>> import numpy as np >>> from scipy.integrate import odeint >>> from crnsimulator import get_integrator >>> odesys = get_integrator(filename, function = odename) >>> odeplt = get_integrator(filename, function = 'ode_plotter') # Simulate >>> p0 = [1e-6, 2e-6, 5e-6] # order of svars >>> time = np.linspace(0, 1e8, num = 10_000) >>> ny = odeint(odesys, p0, time, (None,), atol = 1e-10, rtol = 1e-10).T # Plot >>> odeplt(`ozzy.pdf`, time, ny, svars) ``` ... or include the prebuilt integrator in you own script (like the crnsimulator exectuable): ```py >>> from crnsimulator import get_integrator >>> integrate = get_integrator(filename) >>> integrate(args) # args = <argparse.ArgumentParser()> ``` ## Installation ```sh ~$ python setup.py install ``` ## Version v0.9 -- code cleanup * removed networkx dependency * moved plotting libraries and functions into a separate file to avoid automatic import. v0.8 -- beta status * now using logging * python >= 3.7 only * improved header documentation * using entry_points for crnsimulator script * set defaultrate = 1 (new postprocessing strandard) * new commandline arguments: labels, labels-strict * support the constant concentration flag [oscillator.crn]: <https://github.com/bad-ants-fleet/crnsimulator/blob/master/tests/crns/oscillator.crn>
