WebIt is known that knot Floer homology detects the genus and Alexander polynomial of a knot. We investigate whether knot Floer homology of detects more structure of minimal genus Seifert surfaces for K. We de fine an invariant of algebraically slice, genus one knots and provide examples to show that knot Floer homology does not detect this invariant.
