The independence of the efficiency of ANCHOR from the amino acid composition of the binding sites.

Nint shows the number of interacting residues in the short disordered binding sites, Nfound shows the amount of these that are correctly found by the predictor. As there are types of amino acids that are rare, Fisher's exact test was used to calculate (two-tailed) p values to determine if the predictor works significantly better or worse for certain amino acid types with high p values corresponding to no significant difference.
