Announcing SPARX v2.0

We are pleased to announce a release of a new single particle package SPARX with EMAN2 as its essential dependency. Both components together with all other necessary dependencies are available through a single installation step:

The software is introduced in:

Main features include:
•       New generation of 2D and 3D alignment protocols.
•       Ab initio structure determination programs.
•       Resampling methods for investigation of structural heterogeneity (3D variance).
•       Advanced code for multivariate statistical analysis (PCA, Varimax),
•       New generation of interpolation methods relaxing the need for oversampling the data.
•       Wiki-based interactive documentation
•       Extensive C++ library of general and EM-specific image operations with Python bindings, thus accessible to Python programmer. 
•       All structure determination applications written as user transparent Python scripts
•       All major scripts parallelized for clusters of workstations using MPI.
•       The Transform Class supports all Eulerian angles conventions commonly used in EM, generates point-group symmetries, and provides definitions of asymmetric units.
•       Package reads/writes all commonly used file formats (SPIDER, Imagic, MRC,…) 
•       New HDF5 data format.  In addition to storing image data, the file headers store data processing information (orientation parameters) and can also store any other information provided by the user.
•       Run-through example of a structure determination project.
