To use this method you must give the program observation data arranged as samples by family. It is important that you spell the family names correctly because the program scans your list of names and scores those that correspond with a standard list.

Pisces has developed software to automate this process, see T-group.

 

If your names do not correspond with those in the list, you will see a message similar to this, indicating that corrections must be made.
