Posterior probabilities of correctly predicting secondary structure types with stochastic pairwise alignment methods as a function of alignment posterior probabilities. The black diagonal shows the identity function. The statistics have been generated on the whole HOMSTRAD database, 'Viterbi' means estimation based on a single, optimal alignment obtained by the Viterbi algorithm, 'Forward' means estimation based on the posterior distribution of alignments obtained by the Forward algorithm.
