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].

[edit] Identification
DM4 files have the extension ".dm4". Their contents start with the version number big-endian, i.e. 00 00 00 04.[1]
[edit] Software
- Digital Micrograph (made part of "Gatan Microscopy Suite") itself
- Bio-Formats
- The DM3_Reader plugin for ImageJ
- Fred Sigworth's importer for Matlab
- DM4Reader by James Anderson, written in Python
