The EMDB Map Format document provides a detailed description of the EM Data Bank (EMDB) map distribution format. This format is used to store and share 3D map volumes derived from various electron microscopy (EM) reconstruction methods, such as single particle averaging, helical averaging, 2D crystallography, and tomography. The format follows the CCP4 map definition, closely related to the MRC map format, and includes specifications for metadata headers, optional crystallographic symmetry tables, and voxel data organization.

For more details, refer to the EMDB Map Format document.
