Summary of basic features that are considered.

Features considered by predictor
Name	Number of features	Description
A	1	Penalty for very short coil
B	1	Penalty for short coil
H R	20	Energy of residue R in a helix
$C_R^i$	140	Energy of residue R at position i relative to C-cap
$N_R^i$	140	Energy of residue R at position i relative to N-cap
Total	302

Each of these features corresponds to a parameter that is learned by our algorithm.
