mfapy is a Python toolbox for 13C-metabolic flux analysis developed by Matsuda and Shimizu lab group in Osaka university, Japan. mfapy supports:
- The elementary metabolite unit (EMU) framework developed by Antoniewicz et al 2007.
- Isotopically nonstationary 13C metabolic flux analysis (INST-MFA)
- Parallel labeling experiment without limitation of number of experiments.
- Metabolic flux, net metabolic flux of reversible reaction, and metabolite concentration could be considered as fitting parameters.
- G-value by introducing the "pseudo" reaction
- Goodness-of-fit analysis
- Parallel performing non-linear optimization jobs using joblib package.
- Automated model construction from model description file

Python 3.9
mfapy requires the packages:
NumPy and SciPy (van der Walt, Colbert & Varoquaux, 2011)
nlopt https://nlopt.readthedocs.io/en/latest/
joblib
mkl-service
mfapy was developed and tested using the PyScripter IDE, and was tested in 64 bit version of Anaconda3 distribution in Windows 10.
- Install 64 bit version of Anaconda3
- Create virtual environment such as named "mfapy" and install required packages
> conda create -n mfapy python=3.9 numpy scipy matplotlib joblib
> conda activate mfapy
> conda install -c conda-forge nlopt
> conda install -c anaconda mkl-service
- Install mfapy Unzip and set as current folder
> python setup.py install
> python setup.py test
Sample python code in 'Explanation_1_13CMFA_toymodel.py' explains how to use mfapy. Detailed explanations are available from docstrings Example python codes are also available.
