GEMMI: A Python Cookbook
General MacroMocelecular I/O, or GEMMI, is a C++ 11 header only library for low level crystalographic .
Because its header only it is certainly the easiest to access and use low level crystalographic C++ library, however GEMMI comes with python binding via Pybind11, making it arguably the easiest low level crystalographic library to access and use in python as well!
What follows is a cookbook of useful Python code that uses GEMMI to accomplish macromolecular crystalographic tasks.

A zoonosis is an infectious disease that has jumped from a non-human animal to humans.
The coronavirus disease 2019 (COVID-19) is one such zoonosis, and is caused by severe acute respiratory syndrome coronavirus 2 (SARS coronavirus 2, SARS-CoV-2, or 2019-nCoV). This is very similar to the SARS virus that emerged in 2003. Its recent emergence has resulted in a WHO-declared public health emergency of international concern.

No-one ever observed a pdb file in nature. The experimental data we build our protein models from is not quite so nicely paramterised. The vast makority of models are fit into electron density maps, mostly produced from macromolecular crystalography or cryo-em.
