bionetgen 0.2.9

A simple CLI for BioNetGen

A simple CLI for BioNetGen

This is a simple CLI and a library for BioNetGen modelling language.

Installation

Use the following pip command

$ pip install bionetgen

Features

PyBioNetGen comes with a command line interface (CLI), based on cement framework, as well as a functional library that can be imported. The CLI can be used to run BNGL models, generate Jupyter notebooks and do rudimentary plotting.

The library side provides a simple BNGL model runner as well as a model object that can be manipulated and used to get libRoadRunner simulators for the model.

The model object requires a system call to BioNetGen so the initialization can be relatively costly, in case you would like to use it for parallel applications, use the libRoadRunner simulator instead, unless you are doing NFSim simulations.

Usage

Sample CLI usage

$ bionetgen -h # help on every subcommand
$ bionetgen run -h # help on run subcommand
$ bionetgen run -i mymodel.bngl -o output_folder # this runs the model in output_folder

Sample library usage

import bionetgen 

ret = bionetgen.run("/path/to/mymodel.bngl", out="/path/to/output/folder")
# out keyword is optional, if not given, 
# generated files will be deleted after running
res = ret.results['mymodel']
# res will be a numpy record array of your gdat results

model = bionetgen.bngmodel("/path/to/mymodel.bngl")
# model will be a python object that contains all model information
print(model.parameters) # this will print only the paramter block in BNGL format
print(model) # this will print the entire BNGL
model.parameters.k = 1 # setting parameter k to 1
with open("new_model.bngl", "w") as f:
    f.write(str(model)) # writes the changed model to new_model file

# this will give you a libRoadRunner instance of the model
librr_sim = model.setup_simulator()._simulator

More documentation and tutorials are in progress.

Environment Setup

The following demonstrates setting up and working with a development environment:

### create a virtualenv for development

$ make virtualenv

$ source env/bin/activate


### run bionetgen cli application

$ bionetgen --help


### run pytest / coverage

$ make test

Docker

Included is a basic Dockerfile for building and distributing BioNetGen CLI, and can be built with the included make helper:

$ make docker

$ docker run -it bionetgen --help

Publishing to PyPI

You can use make dist command to make the distribution and push to PyPI with

python -m twine upload dist/*

You'll need to have a PyPI API token created, see here for more information.
