Iterative phase retrieval algorithm. a Flow chart illustrating the input of X-ray diffraction data, initial phases, application of solvent flattening (support function) and forward and backward Fourier transformations. Pink boxes represent real space and cream boxes represent reciprocal space. b Initial phases were provided from a projection of a featureless tube onto a 2D image
