SP inference. The basepair free energies, , inferred from Molecule 1 force data (red curve) are compared to the true free energies (computed from Mfold, sliding average over bp; turquoise curve) and to the free energies inferred from synthetic data generated from the model (orange curve). (Upper) Complete sequence. (Lower) Magnifications of two regions, one at the beginning of the molecule (left) and one at the end (right). To see this figure in color, go online.
