Distribution of estimated copy numbers. The estimated copy number is calculated for each annotation by averaging the alignment depth along the annotation and dividing the average by 7, the average shotgun coverage. The distributions of all annotations (red), of all hypothetical genes (green) and of all trans-sialidase annotations (blue) are shown. The distribution shows the number of annotations (y-axis) for each estimate (x-axis). The graph to the left (A) shows the peak of the two first distributions at 2. The graph to the left is a zoomed in version of the higher estimates. The average estimated copy number of the trans-sialidases is 16.
