Dragonfly is a software package to analyze single particle diffractive imaging data. The package has the following parts

• An implementation of the EMC single-particle reconstruction algorithm using MPI and OpenMP to merge diffraction patterns of approximately identical particles in random orientations.
• Data stream simulator, that generates noisy single-particle diffraction patterns from a PDB file
• An experimental pattern-classification GUI using some machine learning tools to separate single particle diffraction patterns in experimental data.

More detailed documentation can be found in the Wiki pages.

If you are in a hurry, just clone the repository and follow the Quick start instructions.
