DM4 is an image format used by Digital Micrograph, a program used in transmission electron microscopy, often in order to interface with the hardware made by the company that releases it (Gatan). It contains a large amount of metadata in addition to the image itself. It succeeded DM3. It seems that it has only minor differences from DM3, possibily only limited to use of 64-bit integers as opposed to 32-bit ones and a size count for each tag (section)[1].
