theseus - 3.3.0-14 main

Theseus is a program that simultaneously superimposes multiple
macromolecular structures. Theseus finds the optimal solution to the
superposition problem using the method of maximum likelihood. By
down-weighting variable regions of the superposition and by correcting for
correlations among atoms, the ML superposition method produces very
accurate structural alignments.
.
When macromolecules with different residue sequences are superimposed,
other programs and algorithms discard residues that are aligned with
gaps. Theseus, however, uses a novel superimposition algorithm that
includes all of the data.
