Performance of RMscore and SARAscore in identifying similar tRNA pairs. RMSD are plotted against RMscore (a) and SARAscore (b) for all-to-all pairwise comparison of 175 tRNA structures. Horizontal line (RMSD = 5 Å) and vertical line (score = phase transition value at 0.5 (a) and 0.78 (b)) divide the figure into 4 quadrants. Precision is defined as that the total of the number of points in upper left and the number of points in bottom right divides by total number of points. The precision of RMscore (a) is 0.8771 and SARAscore (b) is 0.7766. TPR is defined as that the number of points in bottom right divides by total number of points. The TPR of RMscore is 0.2205(a) and SARAscore is 0.031(b)
