Detailed Description

template<class StructureType, class FT = double, class MolecularDistance = T_Least_RMSD_cartesian<typename CGAL::Cartesian_d<FT>::Point_d>>
class SBL::CSB::T_Alignment_engine_structures_apurva< StructureType, FT, MolecularDistance >

Base engine for making alignments between structures using Apurva.

It inherits from the generic interface for all alignments and provide its base functionality. It also implements functionality specific to structural alignments, in particular for anaylzing and comparing alignments. The specific functionality concerns:

the molecular distance between the two aligned structures (e.g the lRMSD),
the Distance Difference Matrix (DDM),
the dRMSD of the alignment.

Due to geometric nature of the structural alignment, the structure type requires that its units define 3D coordinates, i.e the Alignment_unit defines methods x(), y() and z().

Template Parameters

StructureType	Representation of a structure : it requires in particular to define the type Alignment_unit for the geometric representation of a unit to align (e.g a residue or a nucleotid with associated 3D coordinates), the type Alignment_unit_rep for indexing the units in the structure, the method size() to return the length of the sequence, and the operator [Alignment_unit_rep] for accessing to the corresponding unit of the structure.
FT	Number type representation used for all statistics except the algorithm score.
MolecularDistance	Distance functor between two molecular structures (default is lRMSD).
