Installation

pympgipe has been built and tested with python 3.10+. To install and use our PyPi package, run pip install pymgpipe

Additional Dependencies

Need at least one of the following solvers (requirements.txt includes gurobi)-

• cplex
• gurobipy

In order to install the solver interfaces in python, you can use pip install cplex or pip install gurobipy. This does not actually create a license, it just installs the python interface to interact with these solvers. Both gurobipy and cplex offer free academic licenses. To install the licenses themselves, refer to the links provided above.

Inputs

To create multi-species community models with pymgpipe, you need two things to start-

• Folder with individual taxa models (either in .mat or .xml format)
• Relative abundance matrix (as a .csv) with samples as columns and taxa as rows. Taxa names should correspond to file names within taxa folder (excluding extension)

Examples of both can be found in the examples/ folder. Individual models for thousands of bacteria can be found and downloaded here.

Outputs

The exact location and names of output files will vary depending on the parameters you pass into each function. However, the default output for pymgpipe's build_models function will look something like this-

* pymgpipe input*
.
├── taxaModels/
│   ├── taxa1.xml
│   ├── taxa2.xml
│   └── ...
├── abundances.csv

# pymgpipe output*
.
├── out/
    ├── reaction_content.csv
    ├── reaction_abundance.csv
    ├── sample_label_conversion.csv
    ├── metabolic_diversity.png
    ├── problems/
    │   ├── mc1.mps.gz
    │   ├── mc2.mps.gz
    │   └── ...
    └── models/
        ├── mc1.xml.gz
        ├── mc2.xml.gz
        └── ...

Here is a breakdown of each output files/directory and their descriptions-

Examples

Clone and run through workflow.ipynb in the examples/ folder (see below)
