COBY is a Python-based software tool for building flat membranes at a coarse-grained resolution. It supports asymmetric membranes, phase-separated systems, multiple bilayers, protein insertion, solvation, and flooding with one or multiple solute molecules of choice.
COBY is versatile, fast, easy to use, offering a high degree of customisation. It can be used either as a Python package or directly from the terminal command line. It efficiently manages multiple parameter libraries (even within the same system), making it developer-friendly.
COBY is continuously under development, and we welcome suggestions for new features, which should be submitted under Issues.

Using pip (requires python>=3.9)
conda create --name COBY python==3.9 ipykernel
conda activate COBY
pip install COBY
python -m ipykernel install --user --name=COBY
Ipykernel allows the user to use COBY environment within the Jupyter notebook.
COBY has been developed and thoroughly tested on Ubuntu Linux. It has also been tested to a lesser extent on Windows 11 and macOS, with all tutorial systems running without issue.
Installation can be tested using the tutorial notebooks, which cover the majority of the functions available in COBY.
For a detailed introduction to the software, please refer to the COBY Documentation.
For a quick reminder of available commands, you can use the Cheat Sheet.
Three tutorials are available as Jupyter Notebooks: one covering the basics, another focusing on more advanced functionalities, and the final tutorial showcasing the systems from the manuscript.
