A set of well-known supramolecular cages were selected from the literature to evaluate and validate cavity detection methods in the supramolecular cage context.

## Benchmarking methods

- KVFinder suite ([parKVFinder](https://doi.org/10.1016/j.softx.2020.100606) and [pyKVFinder](https://doi.org/10.1186/s12859-021-04519-4));
- [Fpocket](https://doi.org/10.1186/1471-2105-10-168);
- [pywindow](https://doi.org/10.1021/acs.jcim.8b00490);
- [POVME](https://doi.org/10.1021/acs.jctc.7b00500);
- [GHECOM](https://doi.org/10.1002/prot.22639);
- [CAVER](https://doi.org/10.1093/bioinformatics/bty386);
- [MoloVol](https://doi.org/10.1107/S1600576722004988).

## System requirements

- [Python 3](https://www.python.org) (v3.10.6): Python is a high-level, interpreted, interactive and object-oriented scripting language. 

- [Python 2](https://www.python.org) (v2.7.18): Python is a high-level, interpreted, interactive and object-oriented scripting language. 

- [openbabel](https://pypi.org/project/openbabel/) (v3.1.1.1): a chemical toolbox designed to speak the many languages of chemical data. A wrapper that is automatically using the SWIG package and provide access to almost all of the Open Babel interfaces via Python.

- [pybel](https://pypi.org/project/pybel/) (v0.15.5): a pure Python package for parsing and handling biological encoded in Biological Expression Language. A lightweight wrapper around openbabel module, that provides a more convenient and Pythonic ways to access the Open Babel toolkit.

- [GHECOM](https://pdbj.org/ghecom/) (21/07/2020): a software for finding multi-scale pockets on protein surfaces using mathematical morphology.

- [MoloVol](https://github.com/molovol/MoloVol) (v1.0.0): a software for volume and surface computations of single molecules and crystallographic unit cells.

- [CAVER](https://www.caver.cz) (v3.0.2): is a software tool for analysis and visualization of tunnels and channels in protein structures.
