Sets of features that are emitted by transitions in the FSM.

Sets of features emitted by FSM transition
Label	Features	Description
#0	0	Coil defined as zero-energy
#1	${\displaystyle {\sum }_{i=-3}^{+3}{C}_{R_{n+i-1}}^{i-1}}$	End of helix processing (C-cap)
#2	$H_{R_n}+{\displaystyle {\sum }_{i=-3}^{+3}{N}_{R_{n+i-1}}^{i-1}}$	Start of helix processing (N-cap)
#3	$H_{R_n}$	Normal helix residue
#4	$H_{R_n}$ + A	Helix after very short coil
#5	$H_{R_n}$ + B	Helix after short coil

R_i denotes the residue at position i in the protein, and n is the current position of the FSM.
