We showed that the C3 algorithm is efficient in calculating cavity volumes on cages with all types of shapes, cavity sizes, and window sizes. The angle-based algorithm of C3 is especially efficient with cages with large windows, where the rolling probe algorithm fails due to the probe escaping from the cavity. Once the cavity calculation is completed, various properties of the cavity are computed for a more comprehensive understanding of the cavity's characteristics and the interaction with potential guest molecules, thereby aiding in enhancing and designing novel hostguest complexes. These properties include aromatic contacts, solvent accessible surface area (SASA), hydrophobicity (MHP) and/or electrostatic potential (ESP) described below.
