Figure 1From: GASH: An improved algorithm for maximizing the number of equivalent residues between two protein structuresGASH flowchart. A flow chart of the Global ASH/NER (OLD) and GASH (New) methods is shown. The key differences between the old and new methods are: the generation of multiple initial alignments, a modified parsing algorithm for generation of sub-alignments, and the further generation of hybrid alignments by crossover.Back to article page
