Description:
The structure of the ripple phase in hydrated lecithin (DMPC) was determined by direct methods using data collected in an earlier synchrotron X-ray study. When the Sayre-Hughes equation or maximum entropy and like-lihood were used to determine phases of a basis set, recognizable features of the bilayer profile could be identified. The subsequent refinement, based on permutation of successive phase clusters, allowed a correct structural model to be visualized directly, by imposing the continuity of the directly-identified bilayer as a basis of accepting new phase terms.
