Edit Labels
The Data editor offers a tool to name and index samples. Press the Edit labels button to open the dialog box shown below.
Define a Suffix that will be the first part of the label and common among all rows. Then define from which number the indexing, which is the other part of the label, should start with (Start index), and also the size of the Step in between each index. Also set the Start row and End row which defines between which rows the labeling should be applied. The default setting will label the rows as: Sample1, Sample2, Sample3 etc. Note that it is possible to label segments of the sheet separately. The row labels should be unique before the analysis of the data is started!
