(A) Histogram of the distribution of the LDA score in 126 ancestral frames (black columns) and in the respective +1 de novo frames (grey columns). With a discriminant score of 17.20, a high percentage (96.8%) of ancestral frames were correctly classified as ancestral (score above 17.20) and a high percentage (97.6%) of +1 de novo frames were correctly classified as de novo (score below 17.20). (B) Histogram of the distribution of the LDA score in 68 ancestral frames (black columns) and in the respective +2 de novo frames (grey columns). With a discriminant score of −34.98, all ancestral frames and all +2 de novo frames were correctly classified as ancestral and de novo, respectively.
