Before any analysis, the required number of empty list forms has to be prepared. This can be done by filling the number of lists to be prepared in the related input field and clicking the "Set" button (all existing lists will be discarded). To add a list form to the existing set of forms, click the large plus button located just after the last list form.
The program expects an input in the form of simple item lists i.e. with one item per line. If the source data are to be loaded from files, the files should be plain text files (no formatting) containing one item per each line or comma-separated items.
The program can import a tabular data set wherein the list items are organized column-wise and separated with delimiters in each row. The delimeter can be one of the characters tab, comma or semicolon and has to be properly chosen before reading the data into the app with the "Read Data" button. If the source data are to be loaded from a file, the file should be a plain text file containing delimiter-separated values. After clicking the "Read Data" button, the values should get properly distributed into the individual input lists. If not, check the delimiter choice and appearance of the data. The problem may also be caused by a presence of additional text lines preceding the data. Such lines have to be removed manually.
