A publishing error was made that removed the field calibration markers from Figures 1, 2, 3, 6 and 7 in our work (Nucleic Acids Research, 2004, Vol. 32, No. 22, 6565–6574). These Figures with field calibration markers are reproduced below and the original manuscript should be consulted for the figure legends and relevant results and discussions. Note that the three field calibration markers are separated by 13.09 G apart from one another with the central marker at g = 2.0056.
