xmipp3.protocols.protocol_reconstruct_significant module¶

class xmipp3.protocols.protocol_reconstruct_significant.XmippProtReconstructSignificant(**kwargs)[source]¶

Bases: pwem.protocols.protocol_3d.ProtInitialVolume

This algorithm addresses the initial volume problem in SPA by setting it in a Weighted Least Squares framework and calculating the weights through a statistical approach based on the cumulative density function of different image similarity measures.
