EMAN 2.02 Release Date



This is a bug fix version of EMAN 2.01.

The EMAN2 binary and source downloads also include SPARX !

Please follow the installation instructions at: http://blake.bcm.edu/emanwiki/EMAN2/Install


EMAN2 includes many enhancements and new features, in addition to being a stable official release.

It includes:

  • Complete graphical workflow interface for single particle reconstruction and other tasks.
  • Qt/OpenGL user interface for 2d & 3d display.
  • Refinements ~5 - 20x faster than EMAN1 possible.
  • Over 200 modular image processing algorithms.
  • Flexible infrastructure allows you to control virtually every aspect of the reconstruction process.
  • Support for all known cryoEM file formats.
  • Project system which organizes data and records all reconstruction info.
  • First version of revamped single particle tomography, including a nice tomographic particle picking tool
  • First version of support for using EMAN2 to seed Frealign refinements, and reincorporate the results.
  • First version of a tool for random conical tilt reconstructions (though this lacks a GUI at present)
  • Supports parallel processing via 3 different mechanisms: multiple threads on a single computer, flexible distributed model and MPI for use on shared supercomputers.
  • Improved CTF correction, which can handle CTF fully automatically on ~95 % of images.
  • Many other improvements, both subtle and profound :-)

Windows users - Please note that while we do our best to periodically test the windows release to make sure it's still functioning, it is far less well-tested than the linux/Mac releases. Please report any problems you encounter.

Mac users, we do not support 10.5 since there are a number of issues with OS provided dependencies not working as they should.
