FreeFlux
========
FreeFlux is a Python package designed for :sup:`13`\ C metabolic flux analysis of biological systems at isotopic steady state or transient state, making it suitable for both heterotrophic and autotrophic organisms. With FreeFlux, you can:
- Estimate metabolic fluxes
- Simulate labeling patterns of metabolite (fragments)
- Conduct constraint-based optimizations such as flux balance analysis and flux variability analysis
Our goal is to increase the accessibility of :sup:`13`\ C fluxomics techniques to researchers in the metabolic phenotyping and engineering community.
To get started, check out our `documentation <https://freeflux.readthedocs.io/en/latest/index.html>`__, which provides an overview of FreeFlux's fundamental functions using a `toy model <https://github.com/Chaowu88/freeflux/tree/main/models/toy>`__. We've also included `tutorials <https://github.com/Chaowu88/freeflux/tree/main/tutorials>`__ for practical models of `E. coli <https://github.com/Chaowu88/freeflux/tree/main/models/ecoli>`__ and `Synechocystis <https://github.com/Chaowu88/freeflux/tree/main/models/synechocystis>`__.
Installation
============
FreeFlux was tested in Python 3.7, 3.8, 3.9 and 3.10. It can be installed using *pip* from PyPI:
.. code-block:: python
python -m pip install --upgrade pip
pip install freeflux
or from source (assuming you have `git <https://git-scm.com/>`__ installed):
.. code-block:: python
git clone https://github.com/Chaowu88/freeflux.git /path/to/freeflux
pip install /path/to/freeflux
Installation within an `virtual environment <https://docs.python.org/3.8/tutorial/venv.html>`__ is recommendated.
Solver installation
===================
FreeFlux requires the numerical optimization framework `OpenOpt <https://openopt.org/>`__ for nonlinear regression. It can be installed by the following commands:
.. code-block:: python
pip install openopt
pip install FuncDesigner
Note that the framework is known to work well in Python 3.7, but may have compatibility issues in Python 3.8 and above. In such cases, please refer to this `link <https://freeflux.readthedocs.io/en/latest/installation.html#dependencies-and-compatibility>`__ for solutions.
FreeFlux uses the modeling language Pyomo to formulate linear optimization problem. By default, solvers are not installed together with Pyomo and should be installed independently. For example, to install the glpk solver, run the following command:
.. code-block:: python
conda install -c conda-forge glpk
Example Usage
=============
A typical workflow with FreeFlux starts by building a model through reading metabolic reactions with atom transitions. Users can then call a handler, such as the fitter, simulator, or optimizer, to perform flux estimation, labeling pattern simulation, or constraint-based flux analysis, respectively. Various methods are provided for these handlers for data input and computation.
Below is an example script that performs flux estimation at steady state using the `toy model <https://github.com/Chaowu88/freeflux/tree/main/models/toy>`__:
.. code-block:: python
MODEL_FILE = 'path/to/reactions.tsv'
MEASURED_MDVS = 'path/to/measured_MDVs.tsv'
MEASURED_FLUXES = 'path/to/measured_fluxes.tsv'
from freeflux import Model
model = Model('demo')
model.read_from_file(MODEL_FILE)
with model.fitter('ss') as fit:
fit.set_labeling_strategy(
'AcCoA',
labeling_pattern = ['01', '11'],
percentage = [0.25, 0.25],
purity = [1, 1]
)
fit.set_flux_bounds('all', bounds = [-100, 100])
fit.set_measured_MDV(
'Glu_12345',
mean = [0.328,0.276,0.274,0.088,0.03,0.004],
sd = [0.01,0.01,0.01,0.01,0.01,0.01]
)
fit.set_measured_flux('v1', mean = 10, sd = 1)
fit.prepare()
res = fit.solve()
