There are two kinds of tab:

• The Master Tab is always accessible and is always the leftmost tab in the window. It is used to prepare your data for analysis (this tab is shown by the A arrow in the figure below).
• The Result Tabs, each showing the result of an analysis initiated from the Master Tab (there are three Result Tabs in the figure, shown by the B arrows).

• B : The Result Tabs, these are result tabs, you can rename them by double clicking on them.
• C: These are the main controls of the master tab, green buttons are for filtering and reordering of data, red ones are for analyzing (more on this).

• E: You will find in most cases the genes vertically and the experiments horizontally.
• F: This is the selected class, shown by a red arrow in the master tab and by a blue one in result tabs. Learn more on class selection here.
• G: This part shows details about the selected class and the available actions for it.
• H: These two buttons determine the view of the bottom table. In most cases, you can choose between the experiment table and the gene table.
• I: This gene didn’t pass the filtering and is excluded from analysis.
