Making your raw data available to the macromolecular crystallography community.

A recent editorial in the IUCr macromolecular crystallography journals [Helliwell et al. (2019), Acta Cryst. D75, 455-457] called for the implementation of the FAIR data principles. This implies that the authors of a paper that describes research on a macromolecular structure should make their raw diffraction data available. Authors are already used to submitting the derived data (coordinates) and the processed data (structure factors, merged or unmerged) to the PDB, but may still be uncomfortable with making the raw diffraction images available. In this paper, some guidelines and instructions on depositing raw data to Zenodo are given.
