ReferenceSuperimposer (biojava 6.1.0 API)

java.lang.Object
- org.biojava.nbio.structure.align.multiple.util.ReferenceSuperimposer

All Implemented Interfaces:

MultipleSuperimposer
```
public class ReferenceSuperimposer
extends Object
implements MultipleSuperimposer
```
Superimposes each structure in a MultipleAlignment onto a reference structure.
Performs a global superposition of the MultipleAlignment in case there is only one BlockSet, and a superposition for every BlockSet in case there is more than one (flexible alignment).
This class uses the SuperPositionSVD algorithm.

Since:

4.1.0

    Description copied from interface: MultipleSuperimposer
    
    Superimpose all structures from a MultipleAlignment. The superposition is done for all individual BlockSets. If there is only one BlockSet.
    At a minimum, this should set the transformation matrices for the individual BlockSets.
    This method only calculates and sets the transformation 4D Matrices. If any score is needed it should be calculated and set separately afterwards with MultipleAlignmentScorer.
    
    Specified by:
    
    superimpose in interface MultipleSuperimposer
    
    Parameters:
    
    alignment - MultipleAlignment specifying the aligned residues (via the blocksets) and the atoms to align (via the ensemble).
    
    Throws:
    
    StructureException
