scores a fragment by secondary structure similarity The score for each position is P(H), P(L) or P(E) if a vall residue is within Helix, Loop or Extended secondary stucture element, respectively. P(H), P(L) and P(E) denotes the probability that a given residue in a query is within Helix, Loop or Extended secondary stucture element. The total score of a fragment is a simple sum of all positions; for N-mer fragment is a sum of N terms
If P(H), P(L) and P(E) probabilities takes only 1.0 and 0.0 values, result of this scoring function should be the same as SecondaryIdentity, although the later one is faster. More...
