Fast alignment of points to a density map using principal components.
Fast alignment of a set of points to a density map using principal components of the map and the points.
This type of alignment is good for low-resolution maps.
Note, that principal components are not well-defined for globular objects, so the method may fail in the case of symmetric structures
