Figure 4From: Clinical phenotype-based gene prioritization: an initial study using semantic similarity and the human phenotype ontologyNoise and imprecision quantification. The color map indicates the probability that the actual causative gene rank, R, is less than or equal to r (y-axis) given the similarity value, S (x-axis), between the actual and optimal patient, that is the similarity between the patient terms with noise and/or imprecision, P act , and the corresponding optimal patient terms, P opt . Similarity values are normalized by the self-similarity between the optimal patient terms so that all values of S are in [0,1].Back to article page
