| METHODS - Evolving data standards for cryo-EM structures
The development of cryo-EM is directly reflected by the growth of cryo-EM strructure depositions contributed worldwide to public data archived. The archiving systems and underlying data standards supporting depostioin, annotation, release, and validation of cyro-EM stuctures and the associated metadata describing cryo-EM experiments have been developed over time to support this growth. Recently, CL Lawson, HM Berman, and W Chiu outlined the history of these systems and described the process by which data standards had been developed. For details, please click the link.
