Eden
Description
The computer program Eden (short for Electron density) is based on a real-space method for crystallography.
The origin of the method came from the analogy between holography and the problem of recovering the electron density of molecular constituents of a crystal. It reins in the techniques of image processing to aid in the search for a crystal structure. The most unconventional feature of the holographic method is that it is a real-space method: it searches for a distribution of electrons in the unit cell that meets all the known constraints on the molecules themselves,
while giving rise to the observed diffraction pattern.
