Direct methods for crystallographic phase determination have been used to solve the projected structure of native glucose-embedded bacteriorhodopsin (plane group p3, a=62.4A) to 6A, without accepting any information from electron micrographs. After defining the origin and enantiomorph and adding one
Non-crystallographic symmetry (NCS) averaging is a well known method for improving the quality of an electrondensity map and thus aiding structure determination. Prior methods of NCS-operator determination based on estimated heavy-atom positions are prone to errors arising from inaccuracies in these
