New EMAN version 1.7 released

[Steve Ludtke]

We are happy to announce the release of EMAN 1.7, a major feature enhancement
and bugfix release. Major changes include:

    *  Major overhaul of parallelism infrastructure (runpar). Now uses
fileserver for both reads and writes in the cluster versions. Fault tolerance
has also improved. If a node dies during a run, the run will continue, and
simply stop using that node. Better job distribution to nodes.
    * Binary release for AMD64, and better support for OSX (still imperfect).
    * New program refine2d.py for generating reference-free class-averages from
a set of particles. Uses a combination of SVD and alignment. MUCH better than
startnrclasses.
    * New program makeinitialmodel.py for constructing 3D models from blobs,
good for making random or deterministic shapes.
    * Greatly expanded and improved AIRS software with Chimera bindings. This
includes tools for locating secondary structure in intermediate resolution maps
(ssehunter.py), docking crystal structures (foldhunter.py), and many other
useful tools.
    * Support for both full and 1/2 maps for icosahedral reconstructions


As usual, EMAN can be downloaded from:

We hope to make an official OSX binary available sometime in the next few weeks.
If upgrading from a previous version, please make sure to fully remove the old
version (rm -rf EMAN) before installing the new version. Please direct any
bug reports or questions to sludtke at bcm.tmc.edu.
