The Variants tab shows the frequency at which all the Variants defined in the Project were observed, for each Sample defined in the Project, at the time of the last computation (Figure 1‑46). This is presented in a convenient tabular form that allows the user to compare the frequencies of the Variants across Samples. This tab is not to be confused with the Variants sub-tab of the Project Tab, which is used to store and edit the definitions of Variants. In addition to the Variants Frequency Table, the Variants tab also contains controls to modify the content and format in which the Variant frequency data is displayed. The customary Mouse Tracker, on the left, is also present to provide additional details as you mouse over the cells and headers of the Variants Frequency Table.
