Table 3 20 features ranked on top using permutation test Z-scores. The features were ranked according to the absolute values of their permutation test Z-scores (see text). Name prefixes " PSSM_", "freq_", "PHD_" and " PSI_" denote PSI-BLAST profile based, amino acid frequency based, PHDsec prediction based, and PSIPRED prediction based features, respectively. PSSM_41 and PSSM_42 denote the two features derived from the last two columns of a PSI-BLAST profile (-Q option), i.e. information per position and relative weight of gapless real matches to pseudocounts.
