Hi Lene, How about using the modulus operator in the QGIS expression?
With modulus you can select any nth line, e.g. assuming that the tool created features where the gid advances by 1 for each feature, you could gid % 2 = 0 selects gid with odd numbers: 0,2,4,6 or gid % 5 = 0 would select every 5th number: 0,5,10,15,20 Hope this helps. Just replace gid with whatever is your primary key column.
