def get_cc
 bb_native = self.dmap.get_bounding_box() bb_solution = IMP.core.get_bounding_box(IMP.core.XYZs(ps))

bounding box enclosing both the particles of the native assembly

and the particles of the model

bb_union = IMP.algebra.get_union(bb_native, bb_solution)

add border of 4 voxels

border = 4*voxel_size bottom = bb_union.get_corner(0) bottom += IMP.algebra.Vector3D(-border, -border, -border) top = bb_union.get_corner(1) top += IMP.algebra.Vector3D(border, border, border) bb_union = IMP.algebra.BoundingBox3D(bottom, top)
 
def get_placement_score_from_coordinates
 Computes the position error (placement distance) and the orientation error (placement angle) of the coordinates in model_coords respect to the coordinates in native_coords. More...
 

Detailed Description

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