It is a broadly based greyscale scientific image processing suite with a primary focus on processing data from transmission electron microscopes. EMAN's original purpose was performing single particle reconstructions (3-D volumetric models from 2-D cryo-EM images) at the highest possible resolution, but the suite now also offers support for single particle cryo-ET, and tools useful in many other subdisciplines such as helical reconstruction, 2-D crystallography and whole-cell tomography. EMAN2 is capable of processing very large data sets (>100,000 particle) very efficiently (up to 20x faster than EMAN1). |

All EMAN2 programs, including GUI programs are written in the easy-to-learn Python scripting language. This permits knowledgable end-users to customize any of the code with unprecendented ease. If you aren't an advanced user, you can still make use of all of EMAN2's command-line programs, all of which start with 'e2'.
