xmipp3.protocols.protocol_helical_parameters module
- class xmipp3.protocols.protocol_helical_parameters.XmippProtHelicalParameters(**kwargs)[source]
 Bases:
ProtPreprocessVolumes,HelicalFinderEstimates the helical symmetry and parameters of a structure. Helical symmetry is defined mathematically as V(r,rot,z)=V(r,rot+k*DeltaRot,z+k*Deltaz) and applied to improve the reconstruction of the volume specimens inthe processing. You can limit the radios of the helix, apply dihedral symmetry and apply Cn symmetry
