Ab Initio macromolecular phasing has been traditionally limited to small proteins at atomic resolution (1.2Å or better unless heavy atoms are present). ARCIMBOLDO constitutes a general method for 2Å data, based on combination of location of model fragments like small ?-helices with PHASER and density modification with SHELXE, distributed over a grid of computers.
