Figure 1.

Model architecture and structure-based labelling. Dashed rectangles/arrows are shorthand for showing an arrow connection for each node in the rectangle. Strands are shown to depict the alternating lipid/water environments of the residues. State labels indicate two things: (i) the sequence label for which the state is valid and (ii) the set of emission parameters. Note that states sharing a label also share the same set of emission parameters. The structure-based labelling is illustrated for R.blastica porin [PDB code 1prn (49)].
