Additional file 2: Figure S1. Distribution of presence and length index in sliding window and random generated. a Comparison of the distribution of the 15,135 sliding window values of the presence index (Fig. 1a—red) to the values of 1,000 random sets of 101 non-ordered genes (grey). Only one of the random sets (0.1%) had a presence index below 0.70, while with the genes ordered according to the human genome 2130 windows had a presence index below this threshold. b Comparison of the distribution of the 15,135 sliding window values of the length index (Fig. 1a—blue) to the values of 1000 random sets of 101 non-ordered genes (grey). The highest random set value was 1.46; 1214 genes of the sliding window approach exceed the threshold. c Venn diagram showing the large overlap between the windows that exceeded the 0.1% frequency threshold for presence and length.
