EMAN2.1

Release Date

2014-11-07

Summary

EMAN2.1 has been officially released. While some minor improvements remain to be made, all major bugs have been fixed, and the system is quite stable for both single model gold standard refinements and 3-D classification. We now encourage everyone to upgrade.

Description

This is the official release of EMAN2.1, a general purpose greyscale scientific image processing suite, with a primary focus on biological transmission electron microscopy. See http://blake.bcm.edu/emanwiki/EMAN2 for more information.
