Features of the sub-models

Model	Unit position	Description
KemaSelf	1–5	Secondary structure and solvent accessibility of a center residue;
	6–11	Physio-chemical properties of a center residue;
	12–31	Secondary structure and solvent accessibility of residues with 0 < d ≤ 2;
	32	Amino acid entropy of a center residue;
KemaNeiOne	1–6	Secondary structure of the residues with d = 1;
	7–10	Solvent accessibility of the residues with d = 1;
	11–22	Physio-chemical properties of the residues with d = 1;
	23–24	Amino acid entropy of the neighboring residues with d = 1;
	25–26	Labels to denote the exceeding of the N-terminus or C-terminus of the chain.
