Simplification of the target and models.
(A) Target T0531: SSEs are colored in rainbow and one pair of residues where two SSEs interact
with each other (defined as interaction) are highlighted in magenta. (B) Simplified T0531: the
SSEs are represented by vectors and the interactions are represented by pairs of points
illustrated by the purple dots. (C) A model for T0531 (TS399_4) colored in rainbow according
to the target SSE definition with the same interaction defined in the target highlighted in magenta.
(D) Simplified model TS399_4.
