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.
