We apologize that due to (1) security issues associated with having Python 2.7 in the code and (2) a lack of funding for upgrading the software, the Protein Geometry Database (PGD) will be unavailable for an unknown period of time starting in September 2020. If you are interested in using the PGD and have a potential idea for where it can be hosted, please contact Andy Karplus at andy.karplus@oregonstate.edu.
