Distribution of SNVs, insertions, and deletions along the C. elegans genome for Hawaiian isolate CB4856. Segmented rings on the outside represent the six C. elegans chromosomes. Going from outside to inside, the line plot shows SNV density (inward pointing peaks = higher density), histograms represent the density of deletions (also drawn inwards), and the heatmap depicts the density of insertions (dark red = higher density) detected in the Hawaiian isolate CB4856. Note the generally higher density of SNVs towards the telomeres and the presence of chromosome-internal peaks on chromosome IV and V. Data points for this image were automatically generated by CooVar using the --circos option. Circos was then used to generate the image. Circos configuration files necessary to create this type of image are provided with the C. elegans test data set at http://genome.sfu.ca/projects/coovar/ webcite.
