The SAMPL7 host-guest blind challenge provided a platform to test the reliability of computational methods and tools to accurately predict binding free energies. Since hosts in the cucurbituril and cavitand families have been featured in previous SAMPL challenges (and likely in future challenges) these provide a mechanism to assess how the field progresses across a series of challenges. In addition, the amount of attention these have received helps us identify some potential lessons learned and give suggestions for improvement.
