Genes within high-scoring neighborhoods are more highly and variably expressed. (A) The TNS and expression intensities in this scatterplot are based on the 61 tissues of the Microarray Atlas. Red line denotes best linear fit. (B-D) Boxplots of gene expression variances stratified by TNS are computed for (B) the Microarray Atlas, (C) the Six-Tissue RNA-Seq Atlas, and (D) the Duplicate-Free Microarray Atlas. The width of each box plot represents the total number of genes with best associated TNS in the given range of TNSs. The whiskers of each boxplot denote the range of the data, the circles mark outliers, and the boxes mark the quartiles above and below the median (center line).
