Alternatively, you can press Edit and edit the script which will specify the separator for each parsed line. It is possible to use line number in the script.

By pressing Preview one can bring up the view of the current annotations table (which is produced from the input file with the specified parameters values). The input file contents will also be shown at the bottom part of the dialog.

When all the roles are specified, press Run. With the Add to project checkbox specified and a Sequence View opened, on success you will see the Sequence View with annotations linked:
