cctbx.symmetry_search module¶

class cctbx.symmetry_search.possible_symmetry(r, d, symmetry_agreement, status)¶

Bases: object

accepted = 0¶
change_origin(origin)¶
fmt3vec = '%.3f,%.3f,%.3f'¶
rejected = 2¶
set_components_of_global_origin(origin)¶
unsure = 1¶
class cctbx.symmetry_search.shift_refinement(f_obs, fc_in_p1, initial_shift)¶

Bases: object

cross_correlation_peaks()¶
find_centring_translations()¶
find_space_group()¶
grid_resolution_factor = 0.4¶

possible_point_group_generators()¶
symmetrised_structure_factors(x=None, delta=None)¶
class cctbx.symmetry_search.symmetrised_shifted_structure_factors(miller_set, f_c_in_p1, x, compute_gradient=False)¶

Bases: object

misfit(f_o_or_f_o_sq)¶
