**September 20, 2024** – Researchers and developers now have a powerful new tool for analyzing molecular data with the release of “structure_clustering,” a Python package designed to group similar molecular structures. This innovative package utilizes graph isomorphism to identify clusters of structures based on their connectivity, offering a novel approach to molecular analysis.

“structure_clustering” represents each molecule as an undirected, vertex-labelled graph, analyzing the distances between atoms to determine connectivity. By comparing these graphs, the package efficiently identifies structures belonging to the same group.

Users can leverage this package through its command-line interface, making it easy to cluster multi-XYZ files. Alternatively, “structure_clustering” can be integrated directly into Python code for more advanced applications.

Key features of the package include:

* **Customizable Parameters:** Users can adjust covalent radii and maximum distances for atom pairs through a TOML configuration file, allowing for fine-tuned analysis.
* **Visualized Results:** Clustered data can be visualized using the online tool at https://photophys.github.io/cluster-vis/, providing a clear representation of the grouping results.
* **Wide Platform Support:** Pre-built wheels are available for Windows, Linux, and macOS, ensuring compatibility with various operating systems.

The “structure_clustering” package is released under the MIT License, promoting collaboration and accessibility within the Python community.

**Installation and Usage:**

Installing “structure_clustering” is simple using pip:

“`bash
pip install structure-clustering
“`

To cluster an XYZ file, run the following command:

“`bash
structure_clustering my_structures.xyz
“`

For further details on using “structure_clustering,” consult the package’s documentation.

This new tool empowers researchers with a powerful and user-friendly method for analyzing molecular structures, ultimately contributing to a deeper understanding of chemical systems.
