Δ Δ G predicted by different methods. In (a) - (d), ‘o’ represents non-polar residues, while ‘x’ represents polar residues. R is the Pearson correlation coefficient and δ is the average standard deviation. R is specially calculated for (a) and (d) based on the data set after removing the one outlier prediction. R is slightly changed to 0.543 or 0.515 respectively when the outlier is not removed. The two diagonal red lines represent y=x±1.5.
