Additional file 4: of Overlapping but distinct topology for zebrafish V2R-like olfactory receptors reminiscent of odorant receptor spatial expression zones

Distribution properties and significance of differences. A) The first sheet of the spreadsheet contains the parameter values for the first, second and third quartile of the distributions, i.e. for the radial, laminar height and z-axis coordinates. Half width of distributions was determined as 3rd quartile-1st quartile difference. Distributions of cells expressing V2R-related OlfC and marker genes in adult zebrafish were determined in this study. Values for zebrafish OR and Xenopus V2R were determined from the raw data of the respective publications. B) Maximal vertical distance between two distributions. Pairwise comparison of spatial distributions for different olfactory receptor genes and marker genes of the adult zebrafish (OlfC), and larval Xenopus laevis (V2Rs) to determine the maximal vertical distance between the respective cumulative distribution functions. The range for this maximal vertical distance is pointed out by indicating the minimal and maximal values found. C) The Kolmogorov Smirnov test (see Materials and Methods) was used to determine significance of distribution differences. As a cutoff for significance, we chose p 100 data points). (XLS 51 kb)
