(there were many known problems with this version. Please use EMAN2.1 beta1 ore newer).
This is the first public testing release of EMAN/SPARX 2.1. This is an alpha release, meaning it is not yet feature-complete, and it is expected that a significant number of bugs will be present. It will be followed by additional alpha releases relatively rapidly as the remaining features/functions are put into place. This is a MAJOR new release with significant changes, including retiring (in EMAN2) of the BDB system, new automatic gold-standard refinement, etc.

Another new version of the linux binaries was silently updated on 7/7/13. These new binaries are more backwards compatible, and should work on clusters running older versions of CentOS, as well as new Linux distros.
Note that a new version of the linux binaries was silently uploaded on 7/4/13 despite the date below. This fixes a couple of trivial issues with the initial binaries uploaded on 7/2.
Also note that these binaries are unusually large due to debugging enabled, which will help us track down any problems. Later versions will be smaller again.
