Detailed Description

• The solutions are chosen by sorting the database according to the parameter orderby
• The models are aligned and clustered by RMSD

Note

Member Function Documentation

def IMP.multifit.cluster.AlignmentClustering.do_clustering	(		self,
			max_comb_ind,
			max_rmsd
	)

An IMP.ConfigurationSet is built using the reference frames for all of the components of the assembly for each solution

Parameters

max_comb_ind	Maximum number of components to consider
max_rmsd	Maximum RMSD tolerated when clustering

def IMP.multifit.cluster.AlignmentClustering.get_placement_score_from_coordinates	(		self,
			model_coords,
			native_coords
	)

placement distance - translation between the centroids of the coordinates placement angle - Angle in the axis-angle formulation of the rotation aligning the two rigid bodies.
