It was adopted in 1990 as a standard file structure for the archiving and distribution of crystallographic information. The full documentation and specifications of the format can be found here: text/html 2019-02-18T10:11:58+00:00 Anonymous (anonymous@undisclosed.example.com) https://multigrain.texture.rocks/doku.php?id=fileformat:edf&rev=1550484718&do=diff EDF file format EDF stands for European Data Format and is the typical file format of diffraction data obtained from area detectors. However, some beamlines don't provide their data in EDF format but as tif or mccd. The MGC software cannot process such files so they have to be converted (see text/html 2019-09-04T13:51:32+00:00 Anonymous (anonymous@undisclosed.example.com) https://multigrain.texture.rocks/doku.php?id=fileformat:gve&rev=1567605092&do=diff File format for G-vectors G-vectors are save in a file with a gve extension.
