Figure 7

Scheme depicting the posterior probability density function (PDF) of the values of a property Ω. Continuing with the example of Figure 2, given the previously known group of n amino acids present in the multiple alignment at position i for a given amino acid aa having a value X _Ω,aa assigned for the property Ω, and the average for Ω at position i being μ _9,Ω,6 , then the shadowed area represents the probability that the amino acid aa could be present at the position i, according to the property Ω.
