[3dem] New IMAGIC 4D release

[Sacha De Carlo]

... and the greatest new feature is that the license is finally going to be FREE, right?!?!?

IMAGIC-4D
release    
(www.single-particles.org/methodology) 
A
new
version of IMAGIC will be released on
the 15th of March 2010. 


Whereas
IMAGIC programs (since 1980) will automatically loop over stacks of 2D
images, the
new program versions will also automatically loop over stacks of 3D
volumes present
in an IMAGIC input "4D file".  
All
3D
operations are now in-core ensuring fast processing avoiding
unnecessary input/output
operations. The extended IMAGIC 4D file format remains compatible with
the
previous IMAGIC-5 format. All time-critical programs exploit MPI
parallelization allowing for millions of input images to be processed
efficiently.  
Some
IMAGIC-4D commands: 
MSA-RUN:
MSA eigenvector data compression (high speed parallelization with
parallel I/O
through local scratch files; terabyte-sized files - containing millions
of
images or 3D volumes - can now be processed.  
THREED-RECONSTRUCTION
(TRUE 3D): Reconstruction of multiple 3D volumes using the "exact
filter"
algorithm and our new 3D-deconvolution algorithm. Produces stacks of 3D
reconstructions. CPU needs scale proportionally with the number of
input
images.  
M-R-A
(multi-reference alignment): MPI-parallelized alignments and Euler
angle
assignments with respect to references from multiple 3D volumes.
Various new
alignment options (including "brute force").  
ANGULAR-RECONSTITUTION:
Euler Angle assignments and refinements with respect to multiple 3D
volumes as
anchor sets. 
"IMAGIC
4D" runs on: Linux/Unix, MAC OS X, and MS Windows XP/7 (32 and 64 bit).
