equilibrator-pathway
Pathway analysis tools based on thermodynamic and kinetic models.
This package can run two different pathway analysis methods:
- Max-min Driving Force (MDF)1:
objective ranking of pathways by the degree to which their flux is constrained by low thermodynamic driving force.
- Enzyme Cost Minimization (ECM)2, 3:
estimating the specific cost in enzymes for sustaining a flux, given a kinetic model.
Installation
The easiest way to install equilibrator-pathway is PyPI (and we recommend using a virtual environment):
virtualenv -p python3 equilibrator
source equilibrator/bin/activate
pip install equilibrator-pathway
or, if you prefer installing with conda:
conda install -c conda-forge equilibrator-pathway
The following example Jupyter notebook
can help you get started.
If you only want to try out MDF or ECM without installing anything locally, we have
a simple web interface for you at eQuilibrator 4.
