Hawk is a software package for the analysis and phasing of diffraction patterns from single particle diffraction experiments.
The software handles all steps leading from a raw diffraction pattern to a reconstructed image including geometry determination, background correction, masking and phasing. It works for 2D and 3D data and includes support for graphics processing units using CUDA, which speeds up processing by orders of magnitude compared to a single central processing unit. It is applicable for any type of coherent diffraction imaging (CDI) experiment which fulfils the oversampling condition. Hawk implements numerous algorithms and is easily extended. This, in combination with its open-source licence, provides a platform for other groups to test, develop and distribute their own algorithms.

Hawk runs under Linux, Mac OS X, Microsoft Windows and is available under the GNU General Public License from http://xray.bmc.uu.se/hawk.
The development can be followed at Github.
