The single commonest error in Gannet arises from mis-setting the switches onofforder or WaterPositive in GannetPreinitialise.m. These switches correspond respectively to whether the first average is an edit-ON or edit-OFF average, and whether the residual water signal is positive or negative with respect to the spectrum (which is a largely stable outcome depending on what water suppression scheme is used). In the cases of this dataset (right), the Cr signal (bottom left) is phased positively, so WaterPositive is set correctly, but the edited difference spectrum (top left) is negative, so onofforder needs to be flipped.
