3D-BLAST performance with
E values on the protein query set SCOP-516. (a) The relationship between 3D-BLAST E values and the root mean square deviation (rmsd) values of aligned residues. The average
rmsd values with E value below e^{-10}, e^{-15}, e^{-20}, and e^{-25 }are 3.57 Å, 2.85 Å, 2.37 Å and 2.25 Å, respectively, based on 22,415 protein structures
randomly selected from the 516 returned lists. (b) The relationship between E values and the percentages of true (black) and false (gray) function assignment. The
correct percentages of the superfamily assignments with E values below e^{-10}, e^{-15}, e^{-20 }and e^{-25}, are 95.26%, 97.67%, 99.31%, and 99.75%, respectively. The coverage values of the
function assignment are 98.06% (<e^{-10}), 91.47% (<e^{-15}), 83.72% (<e^{-20}), and 76.74 (<e^{-25}).
