Top-ranked similarities (based on backbone shifts), as measured by a combination of score and contiguity.
Some relevant parameters:  
        HELIX min length: 5     STRAND min length: 3
        shift-tolerance = -10    permissible-violations = 4   max-breaks = NIL   retain-m = 100   best-n = 100
        anglethresh = 0.5    septhresh = 5   min_length = 4   rmsd-tol = 9.9999999999999E12
