ViewData for quantitative analysis of genome features. Analysis of gene and L1 content in the 10 Mb region of mouse chromosome 4 shown in Figure 1C. Shown here is a sample query to calculate the copy number and percentage sequence of LINE-1 and genes in ten 1 Mb windows. Percentage sequence data were calculated per window and for the entire 10 Mb region. The results table can be exported and saved as a tab-delimited file for further analyses.
