Please be aware that due to the subjective nature of secondary structure assignment in borderline cases, dss results will differ somewhat from DSSP. Otherwise, you may need to specify each pair of atoms separately, two by two, as additional arguments to pair_fit. Sequence similarity searches, multiple sequence/structure alignment building, phylogenetic trees and evolutionary conservation analyses, domain parsing, single/multiple chains and loop modeling can be performed in. When the models align well, it suggests evolutionary and functional relationships that may not be discernable. In the field of molecular interactions there have been.
