If you need to reorder your data, switch to the reorder mode by clicking the Reorder button in the top left of the Master Tab. The following view will appear.

Reorder Mode

    This view shows the current order of your classes in the part A of the window. The new order is shown in the B part. To Change the order, simply drag one of the classes in part B to its new position.
    If you need to reorder the samples inside a class, select the class by clicking its panel in part A or B. The contents of the class (i.e. the samples belonging to the class) will appear in the D part of the window. To move one experiment, select it in the table and then use the Up and Down buttons in the C part to bring the sample in the desired position within the class. A reordered class will appear with a small red panel marked R on top of the class's panel in part B.
    When you are finished, apply the changes by clicking the Apply Changes button. The A part and the B part will realign, showing that the reordering was successful. If you leave the Reorder Mode without applying the changes the data are not reordered, but your reorder is kept in memory and will be shown again when reentering the Reorder Mode.
    If you want to reset your reordering, you can use the Reset button to realign the two parts together. Once you click the Apply Changes button, the Reset Button becomes disabled.
